Abstract

A crosslinking agent which is the ungelled reaction product of (a) an aldehyde condensate of glycoluril and (b) a polyol is provided. The crosslinking agent is essentially free of hydroxyl functionality and has a glass transition temperature of at least 15°C. A method for preparing the crosslinking agent is also provided. Further provided is a curable powder coating composition including a solid particulate, film-forming mixture of (A) a polymer containing reactive functional groups having a glass transition temperature of at least 30°C and (B) the previously described crosslinking agent. Additionally provided is a multilayer composite coating composition comprising a base coat deposited from a film-forming composition and a top coat over the base coat deposited from the previously described curable powder coating composition. Coated substrates are also provided.
