Description & use

PiroCoat A is a one-component ablation paste, which is a water dispersion of synthetic resin and pigments. The paste is produced in the form of a thick, creamwhite mass of high density. It is suitable for application with a spatula or, after its slight dilution with water, it can be applied hydrodynamically as a paint coating. The PiroCoat A coating is non-flammable. In order to change the color, PiroCoat A can be topcoated with decorative water-based paints. Before applying PiroCoat A, the surfaces to be protected should be vacuumed, degreased and slightly moistened with water.

PiroCoat A fireproof paste is intended for sealing service penetrations of certain types of flammable and metal pipes and cables. It is intended for fire protection: mineral wool used as an insulating cover, mineral wool boards in mixed penetrations, as a filling of gaps and expansion joints in walls and floors or as a sealing of plasterboards or filling between them. It has good adhesion to various surfaces, including ceramic, gypsum, mineral wool and metals. PiroCoat A coating is characterized by very good endothermic properties and strongly cools the surface while it is heated by the flame and blocks its spread under fire conditions. Penetrations seals made with PiroCoat A are classified in class EI.
