A coating composition of a fluorocarbon polymer which cures at ambient temperatures in which a fluorocarbon polymer in solution is of vinylidene fluoride and hexafluoropropylene and has a weight average molecular weight of about 5,000-600,000; the composition also contains dispersed fluorocarbon polymer particles of the following group polytetrafluoroethylene, fluorinated ethylene/propylene polymer, polyvinyl fluoride, polyvinylidene fluoride, copolymer of tetrafluoroethylene/perflouroalkoxyvinyl ether; a metallic oxide such as magnesium oxide which is an acid acceptor; and an aliphatic or cycloaliphatic polyamine curing agent; preferably, the composition contains a reinforcing pigment such as titanium dioxide. The coating composition is used to provide corrosion and abrasion resistant coatings for large structures in chemical plants, oil refineries, oil drilling platforms, and as a coating for the interior of smoke stacks of large utility companies.
