Abstract
Abstract A water reducible coating composition that by the addition of a solution of water and an amine or ammonia forms a sprayable nonair polluting coating composition that can be dried at ambient temperatures and is useful for coating metal or plastic substrates and in particular for finishing or repairing automobiles and trucks; the coating composition contains a water soluble organic solvent, a binder and pigments. The binder is of (1) an alkyd resin that is preferably the esterification product of soya oil fatty acids, trimellitic anhydride isophthalic acid and trimethylol propane; (2) an alkylated melamine formaldehyde resin, (3) an acrylic dispersing resin and (4) an organo metallic drier.
