Если вы изготовили мангал или приобрели его в the store, then sooner or later you will be asked what kind of paint to protect. If the steel structure is operated on the street, then it will be constantly exposed to fire and atmospheric phenomena. If you do not protect the surface, it will quickly rust.
Composition requirements
The paint must meet certain requirements.it protects the structure when exposed to fluctuations in temperature, humidity and precipitation. It is important to acquire a paint that will have the qualities of refractoriness and will not melt under the influence of fire. Among other things, the composition should not emit harmful substances, with regard to the stage of application and operation. Heat-resistant mixtures can withstand temperatures up to 800 °. Drawing is carried out quite simply, such paints, as a rule, are harmless to health, they can be painted not only the outer but also the inner surface of the product.
Varieties of heat-resistant paints
Paint for barbecue can refer to one ofseveral varieties. Visiting the store, you will be able to find enamel coatings, which are produced under the markings KO 8101 or KO 8111. Heat resistant paints of the grades KO / 08 and KO / 815, as well as an organosilicate composition can be found on sale, among which the OS 12/03 can be distinguished. Quite popular solution due to its cost-effectiveness is heat-resistant varnish KO-85. But it has one drawback, which is expressed in the possible appearance of cracks when exposed to low temperatures. You can choose a resistant impregnation, which contains various oils that do well with low temperatures. However, it should be prepared for the fact that such impregnation requires the need for periodic updates. If you choose a paint for the grill, one of which was described above, it will be able to withstand temperatures up to 500 °. By composition, such mixtures are resistant to high humidity and protect the metal from destruction.
Acrylic paints
Acrylic heat resistant paint for barbecues morepopular for the reason that it is ready to undergo a temperature of up to 650 ° C. During operation, the layer can be briefly affected by temperature up to 800 ° C. In this group of products aerosol cans lead, the main advantage of which is considered to be quick drying. It is important to remember that such paint should be stored under the conditions recommended by the manufacturer, otherwise it may dry for a long time after application.
If you use acrylic paintfor the brazier, then before applying it you do not need to prime the surface, but you should not forget about the treatment of areas that were susceptible to corrosion. The formed layer will be resistant to the effects of salts and oils. After reviewing the assortment, you can choose heat-resistant paint on metal for barbecue different colors. The most popular of them are: black, gray, brown, and also silver.
Overview of the features of heat-resistant powder paints
Powder formulations differ in technology.application. Dry paint should be sprayed onto the surface, and then subjected to high temperatures. At the time of sintering, the composition acquires the required performance, among which is heat resistance. An example would be a powder paint brand S54, which is made on the basis of silicone. This composition is specifically designed to protect the surfaces of stoves, barbecues and barbecues at home. But in everyday life it will be difficult to use it, since it will require the use of a high-temperature drying chamber.
Classification of heat-resistant paints
If you need paint for brazier, then you shouldunderstand the classification of these compositions. They are conventionally divided into categories, among them: areas of use, temperature, composition, and other factors. For example, compositions are used for domestic use, which are designed to operate at a temperature range from 80 to 100 ° C. They can be performed on acrylic or alkyd resin. With their help, it will be possible to form a monolithic protective layer. If we are talking about temperature ranges from 100 to 120 ° C, then it is best to prefer paint based on epoxy resin. On sale you can find one-component paints, which are intended for use at temperatures from 200 to 400 ° C. Among the ingredients are ether-epoxy resins and ethyl silicate. For a temperature range that reaches 750 ° C, it is best to use a mixture in cylinders in the form of sprays. For conditions where the temperature rises above 700 ° C, it is better to use mixtures based on silicone resin.
More on marking
Термостойкая краска для мангала должна labeled with alphanumeric designation. If you saw the two letters "KO", then this indicates that the paint in front of you is based on a silicone binder. After the letter are numbers, the first of which indicates the destination. Thus, the eight speaks about heat resistance. The second and all subsequent figures indicate the catalog number of the development. Before the acquisition is recommended to familiarize yourself with the appointment of the composition. Thus, KO-811 is used for aluminum, steel, titanium surfaces that need protection from corrosion. These enamels are good because they can be applied at low temperatures. As a result, it is possible to obtain a coating that is environmentally friendly, heat and moisture resistant, as well as resistant to alternate heating and rapid cooling. When the temperature rises, the coating acquires even higher qualities of strength.
KO-813 is a compound that is used forprotective staining of metal surfaces exposed to temperatures ranging from 60 to 500 ° C. It is noteworthy that this heat-resistant paint for barbecue has anti-corrosion characteristics, is not afraid of high humidity and sharp fluctuations in temperature. If it is necessary to protect surfaces that are exposed to temperatures up to 400 ° C during operation, then KO-814 should be chosen. The resulting coating has a high resistance to salt solutions, petroleum products and mineral oils. This composition is universal, as it can be used for painting steam pipes with hot steam. KO-8111 is a mixture with which it is possible to paint metal structures heated to 600 ° C. It is resistant to aggressive media.
What to prefer - enamel or paint
If you still haven't decided which paintpaint the grill, you can consider the quality of enamels and paints. After applying the first on the surface, an opaque solid film is formed, which is able to protect from high humidity, but not from exposure to open flame. When comparing heat-resistant enamels and paints, it should be mentioned that the former are more elastic, have high decorative properties, create a more durable coating, and their application is allowed even at sub-zero temperatures. However, the paint for the barbecue (1000 degrees) will not be ignited if it is directly affected by the flame, which is not the case with enamels.
Conclusion
Paint for metal barbecue should be selectedalso by manufacturer. For example, Thermika has been manufacturing similar compounds since 2007. The products of this supplier are confirmed by certificates, and the approximate cost will be 142 rubles. per kilogram.
You can choose heat resistant paintmetal for the brazier brand Dufa, which costs more - from 400 rubles. But allows you to smoothly distribute high temperatures on the painted surface, excluding overheating. The advantage of enamels is the absence of aromatic carbohydrates, which allows the use of the composition indoors.
