摘要 |
The present invention is directed to a curable, water-based coating composition utilized in waterborne coating systems such as a waterborne primer system. The coating composition is the reaction product of a water-dispersible cross-linking agent and a water-based copolymer prepared by free-radical polymerization. The copolymer is the reaction product of a first block and a second block. The first block is the reaction product of a plurality of ethylenically unsaturated monomers. One of the ethylenically unsaturated monomers includes a functional group suitable for reaction with the cross-linking agent. The functional group in the first block is preferably a carbonate, carbamate, or hydroxyl functional group. Other monomers in the plurality include acrylic acid and methyl methacrylate. The first block is also the reaction product of a vinylaromatic hydrocarbon monomer such as diphenylethylene. The second block is the reaction product of a non-functional, ethylenically unsaturated monomer. Methods for preparing the coating composition and a cured film are also disclosed. |
