Abstract
The present invention provides coating compositions with excellent curing performance. Curing can occur very rapidly for excellent cycle time, yet with minimal (if any) foaming. A preferred catalyst system helps to provide excellent initial and follow through cure through the entirety of the coating thickness, even with respect to in-mold coating (IMC) applications. Preferred aspects of the invention provide a composition having zero, or nearly zero, emissions of volatile organic compounds (VOC) when applied and cured.
