Title:
CARBAMATE-FUNCTIONAL, RESINS AND THEIR USE IN HIGH SOLIDS COATING COMPOSITIONS
Document Type and Number:
WIPO Patent Application WO2002068553
Kind Code:
A3
Abstract:
The present invention provides a coating composition containing 1) a carbamate-functional resin having in its structure a hyperbranched or star polyol core, a first chain extension based on a polycarboxylic acid or anhydride, a second chain extension based on an epoxy containing compound, and having carbamate functional groups on the core, the second chain extension, or both; and 2) a second resin containing functional groups reactive with the carbamate groups on the carbamate-functional resin. In one embodiment, the coating compositions are used as a clearcoat to be applied over a basecoat to form a composite coating. The compositions exhibit a combination of desirable properties, such as scratch and mar resistance, resistance to environmental etch, good intercoat adhesion, and high solids.
