ABSTRACT:
Coating lacquers, particularly useful for coating cans, comprise an epoxide resin, a polycarboxylic acid anhydride curing agent, an organic solvent and an accelerator derived from melamine, benzoguanamine or glycoluril. Particularly useful accelerators are the formaldehyde condensates of these materials and their ethers. The coatings are non-toxic and are cured at temperatures lower than conventional.
