Refractory paint reduces the effects of high temperatures on the structure, increasing the fire resistance limit, which can last up to 1 hour or more. Typically, structures are subject to protection, deformation of which leads to loss of strength and destruction of buildings. The use of thin coatings for protection is regulated by the code of fire protection.
If we are talking about fire-retardant thin-layer paint, then it is applied with a thickness of up to 4 mm. On sale you can also find thick-layer compounds, which are represented by mastics and pastes. Their application is carried out by a layer whose thickness is 8 mm or more.
Manufacturer selection
If you need refractory paint, you can choose a composition that swells when exposed to high temperatures. Such mixtures have approximately the same composition, but differ in the nature of additives and fillers. More expensive materials provide a high and long-lasting degree of protection. Specialists do not give specific recommendations for selection, so you should proceed from the technical characteristics of fire resistance.
It is important to pay attention to manufacturers who have been present on the market for quite some time and have managed to prove themselves on the positive side. In a sufficient assortment, the modern industry produces the described materials, among the most popular it should be highlighted:
- Pirex
- DEFENDER
- Kraus
- "Iceberg";
- Orgax.
For reference
Before making a purchase, you need to remember that refractory paint can be water-soluble and organ-borne. In the latter case, we are talking about mixtures that are made on the basis of solvent. They are somewhat more expensive, and working with them is not so convenient, but more outstanding characteristics act as an advantage.
Overview of refractory paints: PIREX blend
This mixture can increase the fire resistance to 120 minutes. The composition is low consumption. The binder is an aqueous dispersion of synthetic polymers. Dilution is allowed, but the volume should not exceed 15% of the total mass. It is important to remember that this refractory paint should be used under certain conditions, they are expressed in compliance with the ambient temperature. You can start working when the thermometer has risen above + 10 ° C, while the relative humidity should not be more than 85%.
In order to achieve an average layer thickness of 1 mm without taking into account losses, it is necessary to apply 1.65 kg of paint per 1 m 2 . At a temperature within 20 ° C, the layer will dry in 12 hours, it is such a period that must be maintained before proceeding with the application of the next layer. This metal refractory paint should completely dry in a maximum of two days, the minimum period of time is 36 hours. After drying, it will be possible to obtain a matte white layer that will protect the structure for up to 10 years. This is true if the coating is not protected from above, otherwise the period will be increased to 15 years.
Reviews on fireproof paint brand "Kraus"
According to customers, fire-retardant paint for metal "Kraus" is quite technologically advanced and durable. The coating can be used for 25 years. Consumers especially note environmental friendliness, because the mixture does not contain substances harmful to health. If necessary, the composition can be tinted in pastel colors, which allows to achieve decorativeness. According to users, this paint is fireproof for metal is a one-component composition, on a water-dispersion basis, which swells with increasing temperature.
It can be used for application to metal and steel structures in order to increase the fire resistance limit. Users like that this paint has a wide area of use, because it can be used in industrial, housing and civil engineering. Fire resistance reaches 90 minutes. A structure protected by this paint can also be used indoors, where the relative humidity does not exceed 80%. In order to achieve the quality of fire resistance, a protective coating should be applied, the thickness of which will reach 60 microns.
Overview of features of heat-resistant Elcon paint for barbecues and furnaces
This paint is fireproof, the price of which is 181 rubles. per kilogram, it is intended for protective painting of equipment, furnaces, heat pipes, barbecues and other surfaces. The heat resistance of the layer will range from -60 to +1000 ° C. Among the additional characteristics, it should be noted resistance to aggressive environments, the absence of the need for preliminary priming, the possibility of application at low temperatures, a service life of up to 25 years, a small flow rate of 350 g / m 2 , which is true if the application is carried out in two layers.
This refractory paint for furnaces has a fairly wide scope, it has anti-corrosion properties and can be used for boilers, metal equipment, oil pipelines, as well as pipelines that will be operated at a wide temperature range. You can use the composition for staining indoors, because after drying the mixture does not emit toxic fumes. Enamel is also used for coloring grills.
The mixture has unique protective properties that protect the surfaces of structures from moisture and high temperatures. These include reinforced concrete, concrete, asbestos and brick substrates. When applied, you can improve the appearance of the object and maintain the quality of vapor permeability. enamel will not lose its properties even with increasing humidity and temperature fluctuations. Due to this, the paint can be used for equipment that will be operated in difficult conditions.
Extra features
The above refractory metal paint for barbecue has resistance to aggressive environments such as stray currents, solutions of salts, petroleum products and mineral oils. Paint can be applied in an electrostatic field and when the temperature drops below zero.
Conclusion
If you need a refractory paint for barbecue, then you can also pay attention to the products of the Elkon company, which is used for anticorrosion protection of metal surfaces used in wet conditions and with a possible temperature difference. Application of the composition can be carried out on the exhaust systems of automobiles, metal surfaces and engine parts that will be exposed to temperatures up to 800 ° C. This fireproof paint for barbecue is also called heat-resistant.
