Cafco SPRAYFILM® WB3

PRODUCT DESCRIPTION

Cafco SPRAYFILM® WB3 is a water based intumescent coating consisting of polyvinyl acetate resins and fillers for the fire protection of structural steel. It can be sealed and protected with a decorative top coat.

Cafco SPRAYFILM® WB3 is applied directly to the contour of primed I and H-section columns, angles, channels and beams, and hollow sections, to provide fire protection for up to 120 minutes. In a fire, a chemical reaction takes place, causing the Cafco SPRAYFILM® WB3 to expand and form an insulating layer which prevents the temperature of the steel rising above a critical level.
