Hegedus, C R; Green, W J

This invention relates generally to a coating for metallic or polymeric composite substrates and more particularly to such a coating which can perform as both a primer and a topcoat. Navy aircraft surfaces need protection from the harsh aircraft-carrier environment, which contains corrosive sea water spray and, on non-nuclear carriers, sulfur dioxide stack gases. Therefore, these aircraft need a coating that will be corrosion-inhibitive as well as chemically resistant, weather-resistant, flexible, even at low temperatures, and have good surface adhesion. Accordingly, it is a general object of the invention to furnish a coating which will provide corrosion protection to a metallic or polymeric composite substrate while being adherent, flexible, chemically resistant, weather-resistant, and opaque.
