Steel fire protection coatings – raw materials

Fire protection coatings are solvent-free, solvent-containing or water-based coating materials. The latter are mainly used in interiors with increased requirements for indoor air quality.

Thermoplastic organic systems are used as binders – usually based on vinyl acetates, acrylates or epoxides. Active substances are added to these, which react to form an insulating “carbon foam” in the event of fire.

The colouring, especially of the top layer, is achieved by means of added pigments.
