Cafco SPRAYFILM^® WB3 is a water-based intumescent coating consisting of polyvinyl acetate resins and fillers for the fire protection of structural steel.

Cafco SPRAYFILM^® WB3 is preferably spray applied directly to the contour of primed 'I' and 'H' section columns and beams, and hollow sections, to provide fire protection for up to 120 minutes.

In a fire, a chemical reaction takes place, causing product to expand and form an insulating layer which prevents the temperature of steel rising to a critical level.
