ABSTRACT:
A water-base endothermic fire protective material comprising a heat curable thermosetting resin, inorganic fibers, an endothermic inorganic filler, and thermoplastic binder resin is disclosed. The material can vary in viscosity from a putty that is moldable or trowelable into place to a thin paste that can be sprayed to form a flexible and stable fire stop seal or coating. The material with essentially no shrinkage retains strength and adhesion qualities before and after exposure to fire and retains superior resistance to the impact, erosion, and cooling effects of a hose stream used to combat a fire.
