Coatmaster Pyroplast-C100

pyroplast-C is a waterborne intumescent coating for the fire protection of electrical cables. When exposed to heat or fire pyroplast-C expands to form a microporous intumescent foam layer with low thermal conductivity which protects the cable. In tests in accordance with IEC 331-1, pyroplast-C was found to increase the fire survival of the tested cables from 3.7 to 19.7 minutes.
