Paint refractory for metal: a review, specifications, manufacturers and reviews

Paint refractory reduces the effect of high temperatures on the construction, increasing the fire resistance limit, which can last up to 1 hour or more. Usually protection is subject to structures whose deformation leads to loss of strength and destruction of buildings. The use of thin-layer coatings for protection is regulated by a set of fire protection rules.

If it is a fire-retardant thin-layer paint, then it is applied to a thickness of up to 4 mm. On sale it is possible to meet also thick-layered compositions which are represented by mastics and pastes. Their application is carried out by a layer, the thickness of which is 8 mm and more.

Select by manufacturer

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 the additives and fillers. More expensive materials provide a high and long-lasting degree of protection. Specialists do not give special recommendations for selection, therefore, one should start from the technical characteristics of fire resistance.

It is important to pay attention to the producers, who have been present on the market for a long time and have proved themselves on the positive side. In a sufficient range of modern industry produces the described materials, among the most popular should be distinguished:

• Pirax;
• DEFENDER;
• "Krause";
• "Iceberg";
• "Organax".

For reference

Before making a purchase, remember that the refractory paint can be water-soluble and organo-diluted. In the latter case, we are talking about mixtures that are made on the basis of a solvent. They are somewhat more expensive, and working with them is not so convenient, but as an advantage are more outstanding characteristics.

Overview of refractory paints: a mixture of PIREX

This mixture can increase the fire resistance limit to 120 minutes. The composition is low in consumption. An aqueous dispersion of synthetic polymers acts as a binder. 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 observance of 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 of 20 ° C, the layer will dry for 12 hours, this is the period that must be maintained before proceeding with the application of the next layer. This refractory paint for metal must completely dry for a maximum of two days, the minimum period of time is 36 hours. After drying, it will be possible to get a matte white layer, which will protect the structure for up to 10 years. This is true if the cover does not protect from above, otherwise the term will be increased to 15 years.

Reviews about Krauz flame retardant paint

According to customers, Krauz's flame retardant paint is sufficiently technological and durable. The coating can be used for 25 years. Consumers especially note the ecological compatibility, because the mixture does not contain harmful substances. If necessary, the composition can be tinted in pastel colors, which allows to achieve decorativeness. According to users, this refractory metal paint is a one-component composition, on a water-dispersion basis, which swells when the temperature rises.

Use it can be applied to metal and steel structures in order to increase the limit of fire resistance. Users like that this paint has a wide scope of use, because it can be used in industrial, housing and civil construction. The fire resistance limit reaches 90 minutes. The structure protected by this paint can be operated inside the premises, the relative humidity in which does not exceed 80%. In order to achieve also the quality of fire resistance, it is necessary to apply a protective coating, the thickness of which will reach 60 microns.

Overview of the features of the heat-resistant Elcon paint for braziers and furnaces

This paint is fireproof, the price of which is 181 rubles. Per kilogram, is intended for protective staining of equipment, furnaces, heat pipes, braziers and other surfaces. The thermal stability of the layer will range from -60 to +1000 ° C. Among the additional characteristics should be noted resistance to aggressive media, no need for pre-priming, the ability to apply at negative temperatures, a service life of up to 25 years, a small consumption, which is 350 g / m ² , which is true if the application will be carried out in two layers.

This refractory paint for furnaces has a wide enough scope of use, it has anticorrosive qualities and can be used for boilers, metal equipment, oil pipelines, and pipelines that will be operated at a wide temperature range. Use the composition for indoor painting, because after drying the mixture does not emit toxic fumes. Enamel is also used for staining grills.

The mixture has unique protective properties, which make it possible to protect the surfaces of structures from moisture and high temperatures. This can include reinforced concrete, concrete, asbestos and brick foundations. When applied, it is possible to improve the appearance of the object and maintain the quality of the vapor permeability. Do not lose its properties of enamel, even with increased humidity and temperature fluctuations. Due to this, the paint can be used for equipment that will be used in difficult conditions.

Additional features

The above-described refractory metal paint for mangal has resistance to the influence of aggressive media such as wandering currents, salt solutions, mineral oil and mineral oils. The paint can be applied in the electrostatic field and when the temperature drops below zero.

Conclusion

If you need refractory paint for brazier, then you can turn your attention also to the products of the company "Elkon", which is used for the anti-corrosion protection of metal surfaces that are used in wet conditions and with possible temperature differences. Application of the composition can be carried out on the exhaust systems of cars, metal surfaces and engine parts, which will be exposed to temperatures up to 800 ° C. Such a fireproof paint for a brazier is also called heat resistant.
