Description & use

PiroCoat I is a one-component, thick, water-based dispersion of synthetic resin and graphite particles. The paste reacts - it increases its volume under the influence of temperature above 150° C. It is suitable for application with a spatula or brush with stiff bristles. It can be diluted by adding up to 3% water. The coating of PiroCoat I is rough when dry. Use mechanical instruments for thickness measurement, e.g. calipers. The dried coating of PiroCoat I may conduct electricity. In order to change the color, PiroCoat I can be topcoated with decorative water-based paints. Before applying PiroCoat I, protected surfaces should be dusted and degreased.

PiroCoat I fireproof paste is intended for fire insulation and sealing and fire-resitant protection of penetrations through walls and floors of steel, copper and cast iron pipes without insulation or insulated with PE foam (in combination with Piro Multitube PM fireproof tape). It can also be used to protect penetrations through walls and floors, small diameter plastic pipes, stabilized with glass or aluminum. The coating made of this fireproof mass, under the influence of high temperature, intumesces under fire conditions, creating a foamed, fireproof thermal insulation layer on the protected surface. Penetration seals made of PiroCoat I fireproof paste are classified in class EI.
