  • Coating composition containing polytrimethylene ether diol useful as a primer composition
    Patent number: 6875514
    Abstract: A coating composition comprising a film forming binder of a. an acrylic polymer having pendant groups that are reactive with isocyanate moieties and having a glass transition temperature (Tg) of 10 to 80°C.; b. a polytrimethylene ether diol having a Mn (number average molecular weight) of 500 to 5,000; and c. an organic polyisocyanate crosslinking agent; wherein the coating composition contains pigments and cures at ambient temperatures or elevated temperatures and forms a coating that is sandable and when used in combination with a top coat, for example, a colored base coat and clear coat or a pigmented mono-coat forms a chip resistant multi-layer coating useful for refinishing or repairing automotive and truck bodies and parts.

  • Coating compositions containing highly structured macromolecules
    Patent number: 6432484
    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.
