Abstract
The invention is directed to a two-pack high solids low VOC ambient curable coating composition, which includes cross linking and binder components. The crosslinking component includes a polyamine, a polyketimine, or a combination thereof. The polyamine is provided on an average with at least two amine functionalities per polymer chain and the polyketimine is provided on an average with at least two ketimine functionalities per polymer chain. A reactive diluent in the binder component includes a macromolecule substantially free from acrylate functionalities and having at least two acetoacetate functionalities per the macromolecule. If desired, the coating composition includes a binder polymer. The coating composition of the invention is particularly suited in automotive refinish coatings.
