Powder coatings with catalyzed transesterification cure |
| abstract |
Improved powder coating compositions comprise a hydroxyl functional binder having carboxylic ester functionality and a transesterification cure catalyst comprising an epoxide and a non-acidic nucleophile, preferably onium salts. Resins such as hydroxyl functional acrylic, hydroxyl functional polyester, ester functional polyesters, and methyl succinate esters of bisphenol epoxides transesterify in the presence of an epoxide and phosphonium salts such as tetrabutylphosphonium acetate and yield coatings having exceptional hardness, impact resistance and solvent resistance at bake temperatures of about 300 DEG F. |
