Abstract: The present invention relates to powder coating compositions which can be cured at low temperatures. The powder coating composition of the invention include a unique combination of a branched oligoester polyol and uretdione crosslinking agent which when cured results in a coating binder with desirable hardness, flexibility, solvent resistance, corrosion resistance, weatherability and gloss.

Abstract: The present invention relates to stable aqueous polymer dispersions and a process for their preparation. The aqueous dispersions of the invention have less than about 5 weight percent organic solvent, at least about 30 weight percent solids, a mean particle size of not more than about 400 nm, and a viscosity of less than about 20.0 poise at about ambient temperature.

Abstract: The present invention is directed to an aqueous dispersion of a polyester salt and polymeric vehicles which include the aqueous dispersions of a polyester salt. The polymeric vehicle is particularly effective for providing coating binders in cured primer coatings. The primer coating compositions are useful for multilayer paint coating films which have at least two layers of paint film including the cured primer coating composition film. The use of the primer polymeric vehicles of the present invention in conjunction with one or more additional overlaying top coating film layers provide a multiple layer coatings having improved adhesion and chip resistance.

Abstract: The present invention relates to powder coating compositions which can be cured at low temperatures. The powder coating compositions of the invention include a unique combination of a branched oligoester polyol and triazole blocked isocyanate cross-linking agent which when cured results in a coating binder with desirable hardness, flexibility, solvent resistance, corrosion resistance, weatherability and gloss.

Abstract: The present invention is directed to stable aqueous dispersions of an acrylic modified chlorinated polyolefin and a process for their preparation. The aqueous dispersions of acrylic modified chlorinated polyolefin are effective for use as coatings on treated and untreated polyolefinic substrates.

Abstract: An ambient curing coating composition made from at least two packages wherein one package contains a copolymer having acetoacetoxy groups and glycidyl groups plus an aluminum catalyst and the other package contains a copolymer having carboxylic acid groups plus a strong organic base catalyst.
