ABSTRACT:
A coating composition for metal containers, a method of coating a metal container, and a metal article useful as a food or beverage container are disclosed. The coating composition for metal container interiors and exteriors comprises: (a) a low molecular weight polyfunctional epoxy novolac resin; (b) a phenolic resin; (c) a solution grade vinyl chloride copolymer, a high molecular weight epoxy resin or a mixture thereof; (d) about 60% to about 90% by weight of nonvolatile material of a vinyl chloride dispersion resin; and a nonaqueous carrier. The coating composition is stored as a single unit system from manufacture until use without an unacceptable increase in viscosity.
