摘要： Pigmented, abrasion and corrosion resistant, thermosetting organic solvent solution coating composition comprise: (A) from about 50 percent to about 85 percent of total resin solids of a triol-based blocked polyurethane polyisocyanate having a number average molecular weight in the range of 600 to 4000; (B) from about 15 percent to about 50 percent of total resin solids of an epoxy-phosphate provided by reacting a resinous polyepoxide with at least 0.05 mole of orthosphoric acid per equivalent of oxirane in the polyepoxide; and (C) a corrosion-inhibiting pigment, preferably a chromium-containing pigment, providing resistance to corrosion. These coatings may be applied to the metal surface to be protected, or the metal surface may be protected with another primer which is overcoated with the subject coatings. The subject coatings are then topcoated, especially with pigmented fluorocarbon coatings.

摘要： A coating composition based on a dispersed fluoropolymer resin is provided. The composition includes a vinylidene difluoride-based polymer such as PVDF, an organic solvent and a dispersant. A method of forming a protective coating on a metal substrate with the fluoropolymer resin-based coating composition and a composite material having at least one surface coated with a vinylidene difluoride-based polymer film are also provided.
