High solids can coating compositions based on epoxy resin, crosslinking agent, flexibilizing polyol, co-reactive acid catalyst, and surface modifier

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