Abstract
Ternary condensate finish. The coating compositions described are designed primarily for application to household appliances fabricated from sheet metal for protection against corrosive environments. When pigmented, these compositions are particularly useful as metal primers: although the pigmented finishes are clear, they can be used equally well as top coats. The components consist of an organic film‐forming material composed of an inter‐polymer of styrene with meth‐acrylic acid and an ester of the acid; a drying ester varnish having a resinous epoxyhydroxy‐polyether and esterified drying‐oil fatty acid; and a heat‐reactive urea or other amine resin. Compositions based on these components can be applied by spraying, brushing, dipping, roller coating and flow coating. They are subsequently dried and cured at 350°F for 15–20 min or 30–40 min at 280°F. (909,322—E. I. Du Pont de Nemours & Co., U.S.A.)
