Abstract

A coating composition for application to a substrate for curing thereon to form an ablative coating. The composition comprises a reactive mixture of epoxy and polysulfide resins, an amine curing agent, refractory fibers and inorganic materials serving as a source of one or more Lewis acids and being capable of forming a glassy reaction product when exposed to heat. When applied to a substrate, the solvent-free composition cures to a tightly adhering, flexible coating capable of providing thermal protection in a very high-temperature, erosive environment.
