Abstract
In a coating composition for application to a substrate for curing thereon to form an ablative coating of the type including a reactive mixture of epoxy and polysulfide resins, an amine curing agent, 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, the improvement comprising adding carbonaceous pre-ox fibers thereto in a weight amount between about 15 to 40%. 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.
