A fast curing high solids coating composition that is useful for coating the interiors of cans and a method of applying such high solids coatings to the interiors of food and beverage cans by spraying from a hot-melt spray gun are the subject of this invention; the coating composition is a blend of:
A. a low molecular weight epoxy resin,
B. a liquid nitrogen resin or phenolic cross-linking agent,
C. a flexibilizing polyol,
D. an inorganic or organic monomeric or polymeric acid which acts both as reactant and catalyst, and optionally
E. a surface modifier; and can be rapidly cured by heating at a temperature and for a time sufficient to substantially complete the cross-linking reaction.
