Abstract
A composition suitable for use as a primer coating for a substrate which comprises a halopolymer, an epoxy resin, and an oxide of titanium. The epoxy resin and oxide of titanium are present in amounts effective to provide a primer coating of the composition over a substrate. Preferred halopolymers are ethylene/chlorotrifluoroethylene copolymers and ethylene/tetrafluoroethylene copolymers. Preferred epoxy resins include bisphenol A based epoxy resins and epoxy cresol novolac resins. A preferred oxide of titanium is titanium dioxide. Such compositions are particularly useful as primer coatings for metal substrates.
