Abstract

An intumescent coating system and method therefor are disclosed for thermally protecting a substrate exposed to fire. The instant coating system has a first component which forms a rigid carbonific char foam having toughness, and a second component which forms an insulative carbonific char foam having about half the density of the rigid carbonific foam. The two foams may be separately applied as, respectively, an inner coating layer coated and cured on the substrate, and an outer coating layer coated and cured on the inner film layer. Alternatively, the two foams are provided as a blend to comprise a single coating layer which is coated and cured on the substrate. While one foam component protects the substrate from breakthrough and direct exposure to fire conditions, the other insulates to protect it from heating by fire conditions, thus offering flame retardancy at film thicknesses of less than 1.27 mm (50 mils).
