The fireproof swelling of the colors contains polymer intelligent substance, as well as various fillers. During heating around the metal structure, the paint is decorated. With the absorption of heat, pairs and inert gases begin to release, which replace oxygen and block the transfer of heat to the surface. This allows you to reduce combustion processes. A foamed layer characterized by a small conductivity of heat, in this case acts as a heat -shielding screen, which prevents the heating of the structure.
