Over time, the market demand for fire retardant constructions has increased significantly, which, for some time, protects steel components against the dangerous effects of fire. To meet these requirements, our employees have been trained in the application of fireproof coatings, as acknowledged by the certificates issued by the paint manufacturer.
Expanding paints are also fireproof and provide fire resistance from R 15 to R 90 (15 to 90 minutes respectively). They increase the volume of the coating under the influence of temperature. Due to the low thermal penetration and volume changes, the coefficient of mass of the protected element increases, and the coating is able to achieve the fire resistance of the steel.
Expanding paints are sold in the form of kits, which contain:
- base paint- adapts the substrate for the best combination with the main paint,
- main paint – the expanding coating with fireproof properties,
- topcoat – thanks to it, the protected element gains aesthetic qualities by appropriately selected color.
One of the most important parameters of the expanding paint is the thickness of the coating as it directly affects the fire resistance of the protected element. The thickness of the coating is directly dependent on the mass index and the critical temperature.
