Abstract: The present invention is directed to a curable, water-based coating composition utilized in waterborne coating systems. The coating composition is the reaction product of a water-based copolymer prepared by free-radical polymerization, and a cross-linking agent. The copolymer is the reaction product of a first block and a second block. The first block is the reaction product of a first ethylenically unsaturated monomer, acrylic acid, and a second ethylenically unsaturated monomer, methyl methacrylate, as well as the reaction product of a vinylaromatic hydrocarbon monomer, diphenylethylene. The second block is the reaction product of a plurality of ethylenically unsaturated monomers, styrene, 2-ethylhexyl methacrylate, cyclohexyl methacrylate, and carbonate-modified glycidyl methacrylate including a carbonate functional group that is subsequently converted into a carbamate functional group by ammonium hydroxide. The cross-linking agent, preferably a melamine, reacts with the carbamate functional group to establish a coating composition having urethane cross-linking from the carbamate—melamine reaction.

Abstract: The present invention is directed to a water-based acrylic emulsion dispersant to be used as a grind resin to incorporate inorganic pigment into a pigment dispersion for a coating composition. The acrylic emulsion dispersant is the reaction product of butyl methacrylate, butyl acrylate, styrene, methyl ether polyethylene glycol methacrylate, polyethylene glycol methacrylate, and polyphosphoric acid. The present invention is also directed to a method of preparing the acrylic emulsion dispersant. In this method, the butyl methacrylate, butyl acrylate, and styrene are combined with water to establish a first reaction blend. Similarly, the methyl ether polyethylene glycol methacrylate and the polyethylene glycol methacrylate are combined with water to establish a second reaction blend. Next, the first and second reaction blends are polymerized to form an intermediate emulsion polymer containing a hydroxyl group from the functionality of the polyethylene glycol methacrylate. Finally, the hydroxyl group from the polyethylene glycol methacrylate is reacted with polyphosphoric acid to form the acrylic emulsion dispersant which is utilized for efficient wetting and grinding of the pigment.

Abstract: The polyisocyanate ester compound is a branched material having at least two ester linkages, at least four urethane linkages further from the center of the compound compared to the ester linkages, and at least one terminal isocyanate group for each urethane linkage, which isocyanate group may be blocked. The compound can be prepared by first by reacting a polyol compound having at least two hydroxyl groups with a carboxylic acid compound having one carboxylic acid group and at least two hydroxyl groups to form a hydroxyl-functional ester product. The hydroxyl-functional ester product is then reacted with a polyisocyanate compound in which the isocyanate groups have different reactivities. The reaction with the polyisocyanate compound is carried out under conditions so that only one of the isocyanate groups is substantially reactive with the hydroxyl groups of the ester product of the first stage.
