Abstract
Water-borne reaction products of (a) carboxyl-functional polymers; (b) polyepoxides; and (c) tertiary amines are electrocoated to give desirable coatings. The coating compositions can be used with or without crosslinking agents and coalescing aids. The resulting coatings give improved properties, including high degree of flexibility during machining and stamping of the coated articles, corrosion resistance, gloss, hydrolytic stability, and are stable and nonadulterating in contact with foods and beverages.
