BRANCHED POLYMERS AND COATING COMPOSITIONS MADE THEREFROM

Document Type and Number:

WIPO Patent Application WO2005026268

Kind Code:

A3

Abstract:

This invention relates to rapid curing coating compositions that are particularly useful for automotive OEM and refinish applications. The coating composition includes a crosslinkable component that contains a novel highly branched acrylic polymer, and a crosslinking component that contains conventional crosslinking agents, such as polyisocyanate and melamine. This invention is also directed to a process for producing coatings from the rapid curing coating compositions. These compositions are especially useful in providing hard highly crosslinked coatings.
