Corundum - thermal paint developed by Russian specialists and a new word in thermal insulation of any surfaces. Some types of this paint work even at temperatures above 500 degrees. And all because the material is not combustible.
Easy to apply, Corundum is a thermal insulation that lasts for a long time, from 15 years, and in terms of heat preservation replaces an additional wall of one and a half bricks.
Thermal paint is a unique development that gives protective properties to the walls of buildings, facades, concrete slabs. Using corundum paint, you save money on thermal insulation.

According to its composition, it is a suspension, water-based or varnish-based, which covers various surfaces well, even with irregularities. The consistency of the paint is pasty, the color is gray or white. It is convenient to work with a brush, roller or sprayer. The greater the thickness of the thermal paint, the higher the thermal protection will be. Its service life is from 15 to 40 years.

Insulation paint - multifunctional. It keeps heat well, does not allow water to penetrate into structures, and protects against mold formation. Corundum thermal insulation extends the service life of pipes, tanks, refrigeration equipment, air conditioners. Keeping warm is the main purpose of thermal paint, so it is indispensable for thermal insulation of pipes. The materials currently used are short-lived and harmful to humans. Pipes covered with corundum thermal insulation endure exposure to precipitation and sunlight.

According to sad statistics, a huge number of fires occur through the fault or with the direct participation of heat-insulating materials. Often the walls are lined with combustible thermal insulation, and in case of fire, fire with lightning speed with the help of this insulation spreads throughout the building, spreads to the roof and neighboring entrances. To prevent this from happening, use heat paint. It is an inexpensive, safe in all respects material that does not support combustion.

Liquid thermal insulation Korund passed climatic tests, which showed that the effectiveness of protection of coated products is maintained for at least 10 years.

Thus, ultrathin thermal insulation Corundum is an effective technological material that meets all the requirements that apply to this class of thermal insulators. Among its shortcomings, it can be noted that in the presence of performance characteristics inherent in all ultra-thin insulations, it differs in an unfavorable way by a higher price.

An innovative material that appeared relatively recently, but has already managed to attract a lot of attention in relation to itself. Why? The liquid base of ceramic thermal insulation Corundum changes the idea of ​​insulating materials after the first use. The substance forms a fairly thin film, which has protection from an aggressive environment and a minimum thermal conductivity. An interesting point is the weight of the thermal insulation material before and after application. When the composition dries, its weight decreases to an insignificant figure and is almost invisible.

The use of such material as liquid ceramic thermal insulation Corundum has very specific goals:

• Protection from external factors and maintaining integrity;
• Insulation of pipeline systems;
• Thermal insulation of the room.

Korund has made sure that its products are as effective as possible for its customers by presenting the following products to the market:

Classic

It has multifunctional properties and is resistant to temperature runoff (-60/+200 °C) and is able to withstand short-term critical temperature points (up to 260 °C). Designed specifically for the insulation of the main elements of the building: plumbing, heating boiler, walls, openings, facade decoration and other partitions, which protect the premises from climatic conditions.

Facade

This thermal insulation from Korund was created to insulate the facade of the room (residential or not, it does not matter). It has good adhesion to many surfaces, that is, high-quality use is available with almost any facing material. It has a high rate of resistance to weather vagaries and retains a greater amount of heat generated in the room, compared to foam insulation.

Anticorrosive

A unique coating to protect and prevent the effects of rust. It has a high rate of resistance to corrosion. The mixture has been widely used for thermal insulation and protection of reinforced concrete and metal structures, pipes, which are used everywhere, as well as other metal products used in construction. It boasts such an opportunity as applying the mixture to the surface without first removing traces of plaque and rust.

Winter

Insulating coating, which is designed for conditions with low temperature properties. Thanks to its special composition, it is resistant to adhesion from surfaces after application. Including those surfaces that have a different basis - liquid and solid. In addition, such a coating protects well from the effects of alkali, salts and many acids.

The use of liquid material - ceramic thermal insulation Korund

The use of such a heat insulator does not require special expensive tools. A standard air gun will work well. It is also possible to work with such improvised tools as a roller and a brush. The application itself is simple and fast. The coating that forms the heat insulator from Corundum is even and seamless. This property has a good effect on the preservation of heat.

Liquid thermal insulation Corundum is a kind of coloring material, after application of which, a high-quality ceramic thermal insulation layer is formed on the surface, which also protects the surface from the negative effects of corrosion.

What is liquid thermal insulation Korund

Do you need to carry out internal thermal insulation of the walls of the room, while you want to lose a minimum of free space? Or do you need to isolate the walls from the outside, but at the same time you want them not to lose their attractive appearance and so that a minimum of money is spent on such insulation measures? Then the only correct solution would be the use of liquid thermal insulation Corundum.

Residents of our country have been living in houses with non-insulated walls for many years. And all this because they are afraid of a long, laborious and expensive process of warming. But today there is a material that can effectively, quickly and inexpensively solve this problem. And this material is liquid corundum thermal insulation. If you go through hardware stores, you can find a lot of ceramic-based heat-insulating materials. But relatively recently, scientists have developed such a heat-insulating material that is better in its technical and operational characteristics than analog materials, while its cost is no different.

Scope of liquid thermal insulation Korund

Due to the fact that Corundum thermal insulation has a liquid consistency, it has a lot of advantages over its direct counterparts, since it can be applied to a wide variety of surfaces:

• Roof;
• window slopes;
• Pipes;
• Facades of buildings;
• Various kinds of containers;
• Internal and external walls;
• Cooling chambers.

In order to prevent any condensate from forming on the surface of the pipeline, and hot water to come to you with meager heat losses, it is recommended to treat the pipes with Corundum liquid thermal insulation. The duration of the operational period of such a coating is equal to 15 years, such thermal insulation can withstand significant temperature fluctuations from -50 to +250 degrees, no analogue can boast of such technical and operational characteristics, and this is subject to the relatively low cost of the material.

Advantages of liquid thermal insulation Korund

The main advantages of liquid thermal insulation Corundum include the following positive points:

• The application process can be carried out independently, for this a regular brush or sprayer can be used;
• Just one millimeter of liquid thermal insulation Corundum will provide the same properties as 600 mm of rolled thermal insulation material;
• It is considered a waterproof material, is not affected by the negative effects of saline and ultraviolet radiation;
• Provides visual access to the inspection of the isolated surface;
• It is a fire-fighting material that does not support the combustion process. When exposed to 260 degrees, the material is charred, but if the temperature rises to 800 degrees, then the process of decomposition begins with the release of nitrogen oxide and carbon, and these substances stop the combustion process.

Thermal insulation corundum

The ultrathin liquid ceramic thermal insulation Korund offered on the market is the optimal solution for many cases in terms of its product protection efficiency, durability, ease of application, but unfortunately not the price. Ultra-thin thermal insulation Corundum is a water-based liquid composition, the main component of which is a polymer latex composition. Its scope is from covering the walls of buildings and structures to thermal insulation of various types of pipelines (air, water pipes). It is also used for application to various types of industrial equipment.

Properties of liquid ceramic thermal insulation Corundum.

Like all ultra-thin thermal insulations, in addition to direct thermal protection, Corundum also prevents corrosion. In addition, the material has dielectric properties. However, in terms of price-quality ratio, it is somewhat inferior to analogues - for example, Aktorm liquid thermal insulation.

Corundum, like all representatives of this class of materials, has a significant advantage over traditional insulation with mineral wool, as it lays down in a continuous layer, leaving no gaps. In the case of mineral wool, unprotected areas always remain, which are channels for the flow of heat. In addition, Corundum is very simply and quickly applied to almost any kind of surface. In this case, it does not really matter whether it is a plane, a rough wall, or complex-shaped equipment. The composition lays down in an ultra-thin layer, providing maximum thermal insulation, the application process itself is almost the same as conventional painting and does not require much time. The composition can be applied at temperatures up to -10 ° C, which is approximately equal to or even slightly inferior to that of Aktorm thermal insulation.

With all the positive qualities, Corundum thermal insulation is also affordable. You can choose convenient packaging and save on installation: the paint is applied with a sprayer or brush. Consumers who have used Corundum clearly distinguish this thermal paint from similar ones. Even if you don't have special equipment, just putting your hand to the wall covered with Corundum, you will feel warm, while the unpainted wall will cool your hand.

Corundum - the warmth of your home!

Liquid ultrathin insulation (as an analogue) is a new word in the matter of thermal insulation of structures. Standard methods of thermal insulation are still good, but little by little more effective solutions are coming to replace them.

Liquid insulation is just such a solution. It is able to protect the structure from freezing, while being essentially more of a paint and varnish material than a heater in the form in which we usually imagine it.

In this article, we will present to you all the nuances and features of Corundum liquid thermal insulation for consideration.

1 Features of liquid insulation

Liquid thermal insulation Korund is produced by the association of companies Fulleren. They have been manufacturing this material for many years and have managed to achieve quite serious results.

Note that liquid-type thermal insulation has not been invented recently. It is intended for the same insulation work, but it is only reproduced in a unique form.

Standard insulation is a special material with low thermal conductivity. It cannot transfer heat and perfectly delimits zones with different temperatures due to the presence of a large amount of air in it.

That is, the insulation has a certain thickness, it is laid on the surface of the walls, thereby protecting them from the effects of external temperatures. As you yourself know, the working thickness of the plate can reach up to 10 cm or even exceed this figure.

But the characteristics of the heat-insulating material Corundum are completely different. This insulation is not in vain called liquid. If you look at it uninformed, then the composition can be confused with ordinary paint.

Indeed, this type of thermal insulation resembles paint in consistency, is applied like paint, and even the coating forms a similar one. However, after application, an ultra-thin heat-insulating film with unique parameters is formed.

This is possible due to the unique structure of the Corundum material (like y).

1.1 Insulation composition

In addition to the standard name in the form of liquid thermal insulation, this insulation has a different name - ceramic.

It is called ceramic not because it consists of ceramics or forms a ceramic surface. On the contrary, the main filler in Corundum insulation is an acrylic-type polymer, only more dense.

Ceramic insulation incorporates ceramic hemispheres with insulated filling. These hemispheres and allow you to create insulation with a thickness of 1-2 mm.

However, an ultrathin film does not consist of only hemispheres. It also contains anti-corrosion type additives, polymers, etc.

Together, they form a heater for walls, floors, ceilings, pipes, and in general any structures available to you.

After solidification, the polymer seizes, forming a very strong film, inside it there are frozen spheres, which occupy more than half of the space. They repel any thermal energy, protecting the insulated structure no worse than a mineral wool layer that is quite impressive in size.

1.2 How it works

Instructions for use states that Corundum insulation with a thickness of only 1 mm can replace up to 5 cm of mineral wool insulation. That's really super-thin thermal insulation. But how does she do it?

And everything is very simple. The fact is that when creating the Korund insulation, the developers were initially guided by the desire to eliminate heat loss in all three main areas. And these directions are probably familiar to you.

Heat loss in building structures most often occurs due to:

• Heat transfers;
• convection;
• Radiation (even if it costs).

Heat transfer is quenched by most standard heaters. But at what cost? To level the temperature difference, a person has to use a bulky insulation with a thickness of 5 cm or more.

At the same time, it must be laid on glue or in a special frame, and then veneered. Liquid thermal insulation performs the same functions, only its structure is ten times denser, and the thermal conductivity index is almost zero.

That is, when finishing the walls, the applied liquid in the same way will not allow the air to exchange temperature with their insides, but at the same time, an ultra-thin film acts as protection here.

Convection is the transfer of heat from object to object. An extremely controversial method, because in conventional construction it practically does not play a role.

However, the liquid ceramic heat-insulating material Corundum can completely remove this moment.

But with radiation, things are much better. Thermal radiation standard insulation materials are not capable of extinguishing (for example, inefficient).

That is, they can only take over the radiation, but a certain amount of it will still reach the surface of the walls. Meanwhile, radiation comes from all warm objects, especially from heaters.

For additional protection, it was necessary to combine ordinary insulation with foil. The foil reflected the waves, and the insulation went about its usual tasks.

But the liquid thermal insulation Corundum repels radiation by almost 90%. Residues are simply extinguished and dispersed close to the surface of the walls.

The result is a situation where all three main consumable items are removed by just one ultra-thin protective film. Surprisingly, customer reviews are also completely in solidarity. Corundum insulation really works and does its job well.

1.3 Pros and cons

When choosing thermal insulation, it is important to pay attention to all parameters. Take into account technical characteristics, reviews and even consumption. However, first of all, you need to look at the properties of the insulation. What makes him good, and what, on the contrary, repels you.

Developers do not eat their bread in vain. Corundum insulation has a huge list of advantages and a minimum of disadvantages. So let's deal with them in more detail.

Main advantages:

• Can be applied to walls, floors, load-bearing structures, roofs, pipes, etc.
• The work is done by hand, improvised means are also suitable.
• Dries quickly.
• A thin protective layer replaces up to 5 cm of standard insulation.
• Not exposed to external influences.
• Not afraid of moisture.
• Does not respond to temperature changes.
• Non-combustible.
• An elementary method of application, as in the case of.

And this is not the whole list. Full characteristics can be assessed only after you have the instructions and certificates for Corundum thermal insulation in your hands. But even from it it follows that the material is extremely useful.

What is only worth the fact that it can be applied with a regular brush. That is, any structure that can be reached can be processed.

And now remember the standard processes of insulation. How much time should be spent to finish one column with mineral wool. And what can we say about the surface of the walls, which are surrounded by a large number of pipes?

While Corundum insulation will not cause you such problems. All you need to do is stir it up and put it on the wall. Not surprisingly, the reviews about her are all completely positive.

Main disadvantages:

• Pretty high price.
• Serious expense.

As for the shortcomings, they are quite trivial. Like any innovative material, Corundum insulation is expensive. This is the cost of production.

The second point, which partially overlaps with the first, is the serious consumption of paint. Corundum should be applied in several layers. Accordingly, the consumption of such material will be very serious.

It is desirable to apply at least 4-5 layers on the surface of the outer walls. This is the only way to form a high quality insulation, and be sure that it will not crack or peel off.

2 Types and differences

Corundum insulation comes in several varieties. Each of them has its own technical nuances.

There is a corundum insulation:

• Classic;
• Facade, Facade-Lotus;
• Anticorrosive;
• Winter;
• Fire protection.

Liquid thermal insulation Korund Classic is a standard option that is used almost everywhere. Thermal paint is easy to apply, dries quickly and has good strength parameters.

Thermal insulation Korund Facade is intended for exterior wall decoration. The Facade-Lotus sample is the front, the second level of insulation. Applied for extra protection.

Model Antikor - insulation with enhanced anti-corrosion properties, ideal for protecting wood.

The Winter model differs only in the possibility of application at sub-zero temperatures.

Well, the last option is paint, which swells upon contact with fire, protecting the structure from fire.

What is Corundum insulation, how is it produced, what varieties exist, technical characteristics of the material, advantages and disadvantages, do-it-yourself application features.

Description and features of the production of Corundum

Liquid heat insulator Korund is a mixture of acrylic binder and ceramic microspheres with the thinnest walls, which contain rarefied air. Acrylic binder is made using fixatives and catalysts.

Microspheres have a size in the range of 0.01-0.5 millimeters. Also, various additives are additionally introduced into the product, which are designed to enhance its certain qualities. Such a balanced composition gives the material lightness, elasticity, flexibility and extensibility. In addition, Corundum has excellent adhesive ability.

The consistency of the liquid ceramic heat insulator is similar to ordinary paint. In fact, this is a white suspension, which, after polymerization, forms an elastic and durable polymer coating.

Unlike conventional heat-insulating materials, Korund not only well protects a building or any other structure from heat loss, but also prevents metal surfaces from rusting.

Initially, similar ceramic heat-shielding coatings were created by order of NASA for use on spacecraft. After some time, it was possible to adapt these compositions to "earthly" needs. Corundum is the trade name for a product developed by Russian scientists. This heat insulator has all the necessary certificates confirming its quality.

The main varieties of corundum

The tool has several industrial modifications:

• Korund Classic. This is a highly effective substance for the insulation of facades, roofs, walls (inside and outside), window slopes, concrete screeds, hot and cold pipes, steam pipelines, air conditioning systems. Thermal paint completely eliminates the possibility of condensation on the surfaces, and also significantly reduces heat loss.
• Corundum Anticorrosive. This insulation is unique in that it can be applied directly to rusty metal. It is only recommended to remove a layer of loose rust. The tool has anti-corrosion properties - it does not “preserve” rust, but prevents its formation. In addition, Antikor is known for its excellent thermal insulation characteristics.
• Corundum Winter. You can work with this product in temperature conditions up to -10 degrees. It does not freeze and does not polymerize under the influence of low temperature. Note that the permissible minimum rate for applying conventional liquid ceramic heat insulators is +5 degrees. Korund Zima contains acrylic polymers and foam glass microgranules dispersed in them. In addition, flame retardants, pigments, inhibitors and rheological components are added.
• Corund Facade. This thermal insulation is specially designed for application on concrete surfaces. It has enhanced heat reflective properties. You can apply this tool in thick layers, which speeds up the process. Korund Facade is also characterized by good vapor permeability and resistance to weathering. It is allowed to apply decorative facade coatings over the liquid thermal insulation Corundum.

Technical characteristics of liquid ceramic thermal insulation Korund

Corundum thermal insulation material has technical characteristics that allow it to be used on structures of various configurations and purposes. With a minimum thickness, this tool is able to provide a good level of insulation.

Consider the main characteristics of Corundum thermal insulation:

1. Thermal conductivity. In numerical terms, this indicator is 0.0012 W / (m * C). This is significantly lower than many traditional thermal insulators such as foam or mineral wool.
2. moisture resistance. The material does not pass moisture and does not collapse under its influence. Even saline solutions have no effect on Corundum.
3. Vapor permeability. Thermal paint does not create an airtight film on surfaces. It allows air exchange to occur, maintaining an optimal microclimate in the room.
4. fire resistance. The material does not support combustion. When the temperature reaches 800 degrees, Corundum begins to decompose, releasing carbon monoxide and nitrogen. And at a temperature of +260 degrees, the thermal insulation is charred. According to fire safety standards, the material belongs to class G1 (non-combustible) and B1 (non-flammable).
5. Adhesion. By the force of separation, this indicator can be different depending on the type of surface on which Corundum is applied. So, for concrete, this coefficient is 1.28 MPa, for steel - 1.2 MPa, for brick - 2.0 MPa.
6. Operating temperature range. Corundum has a fairly large range and ranges from -60 to +260 degrees.
7. Resistance to ultraviolet. The material is not destroyed by the action of sunlight. Therefore, it can be used even without a protective coating.
8. Biological stability. Mold, fungi, rot do not form on surfaces treated with Corundum. Also, the material is not used for food by insects, rodents.
9. Environmental friendliness. Liquid ceramic thermal insulation does not emit any toxic compounds into the atmosphere even when heated. You can also work with it without the use of special personal protective equipment.
10. Lifetime. This is a durable coating that does not lose its qualities for at least 10 years. It does not crack or break.

Advantages and disadvantages of Corundum

The heat insulator is able to completely fill the micropores of the treated surface. The concentration of the polymerized material is 80%. In addition, coating thermal insulation Corundum has the following advantages:

• Retains heat very well. One millimeter of heat-saving paint is comparable in efficiency to 50 millimeters of roll insulation, for example, mineral wool.
• Ease of application. Corundum is applied like ordinary paint with standard tools: brush, roller, spray gun. It does not emit harmful substances, so it does not require respiratory protection.
• Protects surfaces from damage. Metal coated with Corundum will not rust, wood will not rot and dry out under the influence of atmospheric phenomena, plaster, brick, concrete will not crumble and become covered with cracks.
• Does not attract microorganisms, insects, rodents. Surfaces covered with this insulation will not rot or mold.
• Lightweight insulation layer. The weight of Corundum insulation is incomparable with traditional roll coating. Such thermal insulation will not exert any load on the load-bearing walls and foundation. Therefore, it is possible to apply liquid ceramic insulation even on unstable and fragile structures.
• No seams or cold bridges. Corundum allows you to create a durable seamless coating through which cold cannot penetrate into the room.
• Environmental friendliness and durability. Throughout the entire period of operation, the material does not emit any harmful substances. Therefore, it can be safely used for warming residential buildings, as well as houses where allergy sufferers live.
• Does not affect the geometry of the room. Unlike bulky traditional thermal insulation, Corundum will not affect the size and shape of the building in any way.
• Can serve as an independent finishing layer. Pigments can be added to thermal paint, which allows it to be used for wall decoration without additional decorative coatings.

This liquid ceramic insulation also has certain disadvantages. First of all, it is a relatively high price. Corundum appeared on the domestic market not so long ago, so so far its cost is quite high. However, this disadvantage is offset by the fact that thermal paint is characterized by a long service life and retains heat well.

Also among the shortcomings can be identified the rapid solidification of the material. Therefore, you need to work with him quickly.

Criteria for choosing insulation Corundum

The rights to the trademark "Korund" belong in Russia to NPO Fulleren. The company also has a number of official distributors, for example, TeploTrade LLC, ServiceInvestProject CJSC, Korund Trading House LLC of the Southern Federal District and others. Never buy from dubious sellers.

The optimal state of the Corundum insulation is a pasty suspension of white color. Standard packaging - plastic buckets of different sizes. The manufacturer's information must be indicated on the packaging.

The price of corundum thermal insulation may differ depending on the type of material and the place of sale. On average in Russia, the cost of a liquid ceramic insulation is as follows:

1. Corundum Classic - 375 rubles per 1 liter;
2. Corundum Anticorrosive - 435 rubles per liter;
3. Corundum Winter - 540 rubles per liter;
4. Corund Facade - 400 rubles per 1 liter.

Brief instructions for applying thermal insulation Corundum

To apply thermal paint, you will need standard painter tools - brushes, a roller or an airbrush. Using a sprayer, you can get the best quality of application and low consumption of corundum thermal insulation.

The average thickness of one layer should be about 0.4 mm. Apply each subsequent layer only after the previous one has completely dried. When working with a roller or brush, the average material consumption is about 0.5 liters per square meter.

We apply corundum thermal insulation, following the following instructions:

• Pour the paint into a large container and mix it thoroughly so that the mixture is completely homogeneous. To do this, you can use a drill with a special nozzle. You need to set the average speed so as not to destroy the structure of the ceramic spheres.
• We clean and degrease the surfaces on which we plan to apply Corundum. If it is metal, then we clean off the top layer of rust. We use gasoline, kerosene or solvent as a degreaser.
• We begin to apply thermal paint on completely dry surfaces. The first layer should be the minimum thickness, as it is considered a primer.
• If you use a spray gun or a roller for applying Corundum, then joints and hard-to-reach places will have to be brushed anyway.
• If you use Zima brand Corundum, then work can be carried out at a temperature not lower than -10 degrees. For other types of liquid thermal insulation, the optimum application temperature is +20 degrees.
• It is recommended to create no more than three layers of insulation for optimal results.
• It usually takes about a day for all layers to dry completely. If hot pipes were painted, then polymerization occurs much faster.

The Korund heat insulator looks aesthetically pleasing on surfaces, and therefore can be used as a finish. If you are planning additional painting or plastering of surfaces, then this can be done over layers of thermal paint.

Watch the video review of Corundum:

Corundum is the latest invention of Russian scientists in the field of thermal insulation. The material is widely used for insulation of buildings for various purposes, pipelines and other objects. It is an environmentally friendly and reliable ceramic liquid thermal insulation.

INSTRUCTIONS for applying ultrathin thermal insulation KORUND

CORUNDUM- film-forming coating intended for thermal insulation of metal, plastic and other surfaces with operating temperatures from -60 °С to +200 °С (up to +260 °С in peak short-term mode). CORUNDUM adheres well to all types of surfaces. Insulation work can be carried out on surfaces with temperatures from +7 ºС to +150 ºС.
When working with a liquid heat-insulating coating CORUNDUM special attention should be paid to: Corundum must not be frozen. Before opening the container, make sure that the seals are intact. When preparing the material, do not mix excessively (see paragraph 2 of this instruction). When preparing the material, it must not be excessively diluted with water (see paragraph 2 of this instruction)

1. Surface preparation

The surface to be insulated must be cleaned of dirt, rust, dust, old paint, crumbling elements, etc. Pay special attention so that there is no “loose” rust in the form of a “fungus” on the metal, which, after application CORUNDUM flake off the metal along with the coating. To remove rust from a metal surface, use metal brushes or abrasive wheels to remove a loose layer of rust until a metallic sheen appears.
The surface cleaned from rust is treated with a rust converter, if necessary, it is aged for 2 hours. New metal surfaces may require the removal of preservatives. The finished surface must not contain crumbling elements, must be dry (including non-condensing), must not contain oily and greasy elements, must not be excessively plastic. If CORUNDUM is supposed to be used on ferrous metal surfaces, with an operating temperature of up to +150 ° C, then the surface must first be dedusted and degreased, coated or modified CORUNDUM ANTICORE (preferably e), or treat with primer VL-02 or VL-023 (in 1-2 layers in accordance with the instructions for the primer).
If the coating is supposed to be applied to the surface of non-ferrous metal, then it is necessary to mechanically treat the surface to remove the gloss, remove dust, degrease, treat with adhesive primer VL-02 or VL-023 (1-2 layers).
If CORUNDUM it is supposed to be applied to concrete, brick and similar surfaces; cement-plaster compositions. Clean the surface with a sandblaster, a metal brush or abrasive wheels to remove the gloss on the surface and remove loose and crumbling structural elements.
After mechanical treatment of the surface, thorough dedusting should be carried out using brushes or blowers. After that it is necessary to rinse with water to remove dirt, remaining dust, etc. After complete drying, it is necessary to prime with a deep penetration acrylic primer.
To apply on the front part of the enclosing structures of buildings and structures made of vapor-permeable materials (concrete, brick, etc.), it is necessary to use a modification CORUND FACADE.

2. Preparation of the insulating coating KORUND

CORUNDUM ready for use it must be stirred, if necessary, by adding a little distilled water immediately prior to application to the previously prepared surface. The amount of water depends on the temperature of the application substrate, the temperature and humidity of the ambient air, subsequent operation and other factors. When applied to a surface with a temperature of +7 °C to +80 °C, the amount of water added to the material can be no more than 5% when applied with a brush and no more than 3% when applied with equipment (airless spraying machine). When applied to surfaces with temperatures above +80 °C, it is necessary to bring down the temperature first by applying several primer layers of Korund material, diluted with 40-50% distilled water according to the scheme specified in paragraph 3 "Coating". For detailed recommendations, contact the nearest representative office or the manufacturer. With a long period of storage inside the container, stratification into fractions is allowed.
When using a drill with a paddle nozzle or a mixer (please check with your local Corund representative for equipment selection recommendations) - the maximum mixing speed is - 150-200 rpm. Exceeding the rotation speed will lead to the destruction of the microsphere and a radical decrease (or cancellation) of the efficiency of thermal insulation. coverage.
Using the vertical movements of the blade so as to immerse the thickened part in the liquid, turn on the drill and slowly begin to rotate the blade, mixing the clots with the liquid. Stir until the product becomes like cream. Approximate mixing time - mixer 3-8 minutes, manual mixing 7-10 minutes.
If the task is to eliminate condensate, "fur coats" of frost - the material is applied with a minimum addition of water, with a maximum interlayer gap.

3. Coating

It is recommended to work with a soft brush with long natural bristles or an airless sprayer (check with your representative for recommended brands and models of airless sprayers, as well as recommendations for setting them up).
Small surfaces or complex areas can be coated with a soft brush. Surfaces from 100 m2 can be treated with an airless sprayer with a working pressure of not more than 60-80 bar ( IMPORTANT!!! Not all airless sprayers are suitable for Corundum applications!!! For recommendations on the selection, adjustment and operation of airless sprayers, check with the manufacturer or the nearest Korund representative. See also Supplementary Data Sheet for Airless Sprayers).
It is possible to apply an insulating coating on a surface with a temperature of +7ºС to +150ºС. It is impossible to work in wet weather, because. the material is liquefied by water, and it will not dry out.
For better adhesion of the material to the treated surface, it is recommended to apply a primer layer on the prepared surface with a liquid (like milk) composition of the material, diluted with 40-50% distilled water.
The period of complete drying of one coating layer with a thickness of 0.4-0.5 mm is at least 24 hours at an ambient temperature of over +7 ° C and a humidity of not more than 80% throughout the entire drying time, i.e. 24 hours. The next layer can be applied only after the previous layer has completely dried - after 24 hours at room temperature. A layer of the order of 0.4-0.5 mm (optical density thickness) is obtained with three “passes” of the atomizer, brush. Applying the material with a thicker layer is unacceptable, as this leads to the formation of a moisture-proof film on its surface, which in turn prevents the complete evaporation of the moisture in it, which will lead to the annulment of thermophysical properties and deformation of the coating.
When applying the material to a surface with a temperature of +80 ºС to +150 ºС, the material boils and “seizes” very quickly, so the material must be diluted with water. It is recommended to prime the surface with a 40-50% aqueous solution of the material. IMPORTANT! When applied CORUNDUM on surfaces with temperatures above +80 °C, the thickness of the maximum layer in 24 hours should not exceed 0.5 mm. The hotter the application surface, the more the material is diluted. The diluted material is applied in quick, short strokes, with this application the layer will be very thin. The drying time of each such layer is at least 1 hour. Such layers are applied until the applied material stops boiling on the surface. After that, let it dry for 24 hours. Then the material is applied according to the usual scheme - with the addition of 3% to 5% distilled water in layers up to 0.5 mm with an interlayer drying of 24 hours.
A layer thickness of 0.5 mm can be determined with a “paint comb” type thickness gauge, material consumption of 0.55 l per 1 m2 (approximate consumption when applying a coating with a brush on a flat surface) or thickness of the “optical density” of the material (so that the substrate does not shine through the material) . Material consumption is affected by the type of surface and the method of application.
The total thickness of the coating and the number of layers is determined by thermal calculation or recommendations from certified regional production offices.

The preservation of heat indoors largely depends on the thermal insulation parameters of the building itself and the finishing materials used. Reliably insulate the house - it means to reduce the cost of heating. Today, the construction industry offers many varieties of insulation materials that vary in their characteristics and cost. One of the best options is liquid thermal insulation Korund, which is durable and has excellent thermal insulation properties. Let us consider in more detail the features of the composition, selection criteria and application technique.

The unique composition of thermal insulation is also called heat-reflecting paint, since with a layer thickness of only 1 mm it can have a noticeable energy saving effect. Due to this, the thermal insulation of Corundum is very economical in terms of consumption. The composition of the filler includes microscopic hollow spheres - ceramic, polymer, composite, glass balls, which are filled with rarefied air. Such microparticles can differ not only in composition, but also in the size of microgranules, percentage, uniformity of components, etc.

Externally, ceramic ultra-thin paint practically does not differ from ordinary acrylic-based paint. Despite the fact that today the construction market offers several varieties of ultra-thin insulating compositions, almost all of them have a similar structure:

1. Thermal paint is based on a water-acrylic solution. Its properties make it possible to ensure uniform distribution of heat-insulating components over the working surface. In addition, the composition contributes to better fixing of liquid ceramics.
2. Also, the binder contains various additives that improve the performance parameters of thermal paint. The most common material additives include natural and artificial rubbers, silicone, etc.

Liquid thermal insulation Corundum: technical characteristics and principle of operation

The temperature range for thermal paint varies from -65°C to +260°C. The main technical characteristics are vapor permeability and hygroscopicity of liquid insulation, which can be applied to almost any type of facade material: concrete, stone, brick, metal, plastic, etc.

This material guarantees the removal of condensate that forms on the walls and pipes in the room. The composition of such thermal paint includes special fixatives, catalytic agents, anti-corrosion additives, as well as a binder base on high-strength acrylic. Along with the content of microspheres, this composition is easy to apply and spread over the entire surface, providing good energy saving and thermal insulation performance.

An important argument to buy liquid thermal insulation Corundum is the safety of the substance. Due to the content of natural additives and environmentally friendly components, the treated surface is non-toxic and does not emit any odors. This allows you to use thermal paint to insulate any room. It is possible to create a resistant thermal barrier even in children's rooms or homes where allergy sufferers are located.

The thermal insulation properties of the composition can be achieved in several ways:

1. Through convection, i.e. heat transfer by the thermal paint layer itself. Due to the fact that most of the specific gravity of the liquid insulation consists of hollow balls, convection losses in the composition are quite insignificant.
2. The thermal conductivity of a material, when heat is transferred from a hotter part of the surface to a colder place. In liquid insulation, only 20% of the binder has thermal conductivity properties.
3. Radiation - a phenomenon in which heat transfer occurs through the internal energy of the suspension. In energy-saving paint, microscopic spheres are endowed with the properties of reflection and heat dissipation. Almost 90% of the reflected radiation turns the working surface of the wall into an analogue of a thermos.

Advantages of corundum thermal insulation

Liquid heat-saving paint is an innovative composition that differs from all existing coatings. Among the most significant advantages of its use, it is necessary to highlight the following aspects:

1. The versatility of matter. It can be applied to any kind of surface, including untreated, if indicated on the instructions for use. Specialists use thermal paint for processing brick, concrete, metal, plastic surfaces, as well as thermal insulation of equipment and air ducts.
2. Wear resistance. The applied layer of liquid insulation does not degrade over time. Corundum provides a guaranteed service life of up to 15 years, and with proper care (timely cleaning, high-quality finishing), this figure can be doubled.
3. Ceramic thermal insulation has good adhesion to any type of material, which provides good protection against moisture and air.
4. Substance is steady against the alkaline environment.
5. Liquid thermal insulation provides anti-corrosion protection and minimizes heat loss.
6. Dry coating with thermal paint reliably protects the treated surface from deformation due to temperature changes, atmospheric influences and moisture formation.
7. Ceramic thermal insulation is practical and easy to apply on surfaces of complex geometric shapes.
8. The material is ultra-light, which does not create an additional load on the structure. Due to this property, thermal paint is often used in roofing.
9. The substance is quite convenient to repair, because. in case of minor damage, the old layer can be easily removed, replacing it with a new one.
10. Thermal paint reflects up to 80% of the energy of ultraviolet rays.
11. In addition, liquid insulation is resistant to fire. When heated to + 260 ° C, the applied layer is charred, and when it reaches + 600 ° C, the thermal paint begins to decompose, releasing carbon and nitrogen oxide, which prevents the rapid spread of flame.

Disadvantages of ultra-fine thermal paint Korund

Despite the impressive list of advantages of the material, it is not without some drawbacks. Among them, the following aspects should be highlighted:

1. The high cost of thermal paint.
2. Since ceramic thermal insulation is a relatively new product on the construction market, there is no time-tested evidence that the material meets the stated characteristics.

The main types of thermal insulation

Liquid ultrathin thermal insulation is available for sale in specialized hardware stores in several versions. The entire line of polymer compositions consists of the following types:

1. Thermal insulation Korund Classic is a liquid suspension, which is intended for roofing and facade work. Also, this composition has found application in interior decoration, providing reliable thermal insulation of walls in residential buildings and general buildings. In addition, the classic variety is highly effective for insulating concrete floors, self-leveling coatings, hot and cold water supply communications, as well as window slope insulation.
2. Corundum Anticorrosive is a special composition for anti-corrosion purposes, which can be applied simply to a rust-covered surface, without special treatment. Such thermal paint is characterized by high adhesion to concrete and metal, creating a reliable protective and insulating layer. As a rule, this liquid thermal insulation Corundum is somewhat cheaper than the classical type and is used to create the first base layer of insulation.
3. Facade - a type of heat-saving paint intended for the treatment of concrete surfaces, as well as buildings made of cinder or foam blocks. The composition is applied in a thickened layer, thereby reducing the labor factor for processing surfaces of a large area. This type of thermal paint is usually used for finishing.
4. Winter is a liquid thermal insulation designed for work in the cold season. The principle of energy saving is based on the “thermal mirror effect”, i.e. reflection of the flow of heated air masses. This composition is universal and can be applied to almost any surface at ambient temperatures down to -10°C.

General criteria and features of choice

Ceramic thermal insulation is not yet a fairly common type of coating, due to the high cost of production. However, experts argue that this substance has exceptional performance characteristics, the value of which significantly exceeds the cost of acquisition. To choose the optimal type of liquid thermal insulation, it is important to consider the following features:

1. The first thing that affects the final result of processing with ceramic insulation is the density of the composition. High-quality thermal paint is characterized by an indicator of about 0.6 kg per 1 liter of product. Those. the weight of a standard bucket of 10 liters should not exceed 7.5 kg.
2. It is also worth looking at the container with the solution “in the light” to determine the degree of its separation. A good indicator of the quality and effectiveness of thermal insulation properties will be a dense top layer of the substance. As a rule, ceramic spheres have a light fraction that rises to the top. Thus, the thicker the upper layer, the higher the thermal insulation properties.
3. An equally important selection criterion is the structure of the suspension itself. To determine it, you need to rub a couple of drops of heat paint between your fingers. In the qualitative composition, microgranules of ceramic balls are felt, i.e. the substance is rough.
4. In addition, it is necessary to take into account the color of the liquid thermal insulation. Corundum is produced in white, so gray or yellow paint is a clear indication of counterfeit products.

Application area

Ultra-thin ceramic insulation Corundum is an innovative material that forms a durable elastic coating that reliably protects the surface from moisture, overheating and corrosion. This composition is used in the temperature range from -65°C to +260°C.

The main areas of application of thermal paint include:

• housing and communal services facilities (including processing of pipelines for various purposes, thermal insulation of facades, roofs, windows, walls);
• transport industry;
• oil industry;
• insulation of thermal power structures;
• construction industry.

Ceramic insulation technology

It is necessary to apply ultra-thin thermal insulation Corundum on a previously prepared surface, regardless of the modification of the composition. The basic rules that should be followed before starting painting insulation include the following:

1. If ceramic insulation is intended for wall treatment, the work surface should be cleaned of dust and dirt, and existing gaps and chips should be expanded and filled with cement mortar.
2. Before carrying out painting thermal insulation on concrete slabs, they should be cleaned of "cement milk".
3. It is also necessary to treat the wall with an abrasive wheel, sandblasting machine or a hard metal brush.
4. If it is planned to treat a metal surface, it must be dedusted and degreased (substances recommended by the manufacturer - Solv-Ur, Solvent). For painting objects made of non-ferrous metal, it is necessary to remove the gloss and apply the primer composition VL-02 or VL-023.
5. It is also worth considering that it is necessary to dilute ceramic thermal paint immediately before applying it to the wall.

Important! Mixing liquid thermal paint Corundum is recommended to be done manually. However, for work with large volumes, it is allowed to use a construction mixer, the speed of which should not exceed 200 rpm. Otherwise, there is a risk of destruction of the hollow ceramic granules, which will adversely affect the thermal insulation properties of the composition. As a rule, manual mixing takes 10-15 minutes. When working with a construction mixer, this figure will be 3-7 minutes.

It is also worth considering that it is necessary to add water to some modifications of the composition before starting work, so you need to carefully study the manufacturer's instructions. The volume of liquid depends on the purpose of the thermal insulation, in any case, the required proportions are indicated on the packaging of the composition.

The technique of applying ultra-thin thermal insulation Corundum is carried out in three ways:

• with the help of air spraying devices;
• airless spray method;
• manually - using a roller or brush.

The manufacturer recommends applying the composition in three layers, while the consumption should be 1 m / m 2. When working on thermal insulation with this composition, additional ventilation in the room is not required, as well as the use of special personal protective equipment.

To guarantee the effectiveness of the result, it is important to strictly follow the manufacturer's instructions and fully adhere to the recommendations indicated on the package.
