Abstract:
A corrosion protection applique adapted for applying to an aircraft surface as a substantially complete, bubble-free, wrinkleless coating to replace aerospace paint on the surface, and, in replacing the paint, to provide corrosion protection for the surface by limiting migration of water from a surrounding atmosphere to the surface, the applique comprising a 1-4 mil thick, water vapor barrier stable in hot-wet conditions up to at least 250.degree. F. and selected from a fluorinated terpolymer derived from tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride or a fluoropolymer, the vapor barrier being adapted to substantially reduce or to eliminate transport of water to the surface and a pressure-sensitive or thermally-activated adhesive having low electrolytic, ion transporting properties to enhance corrosion protection by limiting ion transport beneath the vapor barrier, the adhesive being applied on at least one face of the vapor barrier over substantially the entire face for adhering the vapor barrier to the surface, the vapor barrier being tearable and tatterable in the event that the applique begins to peel during flight and being adapted to provide sufficient corrosion protection to replace aerospace paint as a corrosion protection covering or coating for the surface.
