Abstract

A barrier coating having high temperature resistance and insulating properties includes an insulating resin, a flame retardant, and a reinforcing fiber. The insulating resin includes high-consistency silicone rubber, epoxy, or a combination of high-consistency silicone rubber and epoxy. The flame retardant includes a first flame retardant and a second flame retardant, one of the first and second flame retardants including an intumescent. The intumescent includes melamine powder, expandable graphite, or a combination of melamine powder and expandable graphite. The other flame retardant includes ammonium polyphosphate. The reinforcing fiber includes aromatic polyamide, poly-paraphenyleneterephthalamide, or a combination of aromatic polyamide and poly-paraphenyleneterephthalamide.
