Abstract: A composition for use in manufacturing fire and heat resistant components, typically by moulding, comprises a mixture of foamed filler, a liquid binder and one or more frits. The composition may itself be moulded to form such components or may be included in other moulding systems to impart fire and heat resistant properties to a moulding.

Abstract: A coating composition for providing or enhancing the fire resistance of a material. The composition includes a carrier, a polymer base selected from the group consisting of polyepoxide resins and vinylchloride/acrylic copolymers, an inorganic solid substance that gives off water when the composition is heated under fire conditions and two or more frits of different melting temperatures. The first frit has a relatively low melting point and the other, devitrifying frit has a relatively high melting point compared to the first frit, the frits melting progressively under fire conditions to provide a fused protective layer for the material.
