Intumescent Paint

Thin film applied Intumescent paint is a fast method of providing up to 120 minutes fire protection to structural steelwork. Intumescent coatings provide an appearance similar to that of paint, with basic to high gloss finishes now available.

At ambient temperatures Intumescent paint systems remains stable. However in a fire condition, the increase in temperature activates a chemical reaction which then causes the intumescent coating to expand many times its original thickness. This expansion provides an insulating foam-like coating or “char”. It is this “char” that provides the fire protection to the steel work which, in some instances, can be up to 50 times its initial applied thickness. Therefore, secondary casings applied to the steel members must allow for expansion to ensure the intumescent paint system performs correctly.

Intumescent paints whether water or solvent based can be applied by airless spray, roller or brush and will provide up to 120 minutes fire protection. The paint is applied as a thin film layer and is often available with a range of topcoats in different colours so that the designer can achieve their aesthetic needs while providing a suitable fire protection to the steel members.
