    摘要: A crosslinking agent having reactive benzoxazine groups is provided. The crosslinking agent is the ungelled reaction product of a polyhydric aromatic compound and an aminotriazine compound having one or less non-alkylated NH bond per triazine ring. The crosslinking agent is essentially free of hydroxyl functionality and has a glass transition temperature of at least 10° C. Additionally provided is a method for preparing the crosslinking agent. Also provided is a curable powder coating composition including a solid particulate, film-forming mixture of a polymer having functional groups reactive with benzoxazine groups and the crosslinking agent. Further provided is a multilayer composite coating composition having a base coat layer deposited from a film-forming base coating composition and a topcoat layer deposited from the curable powder coating composition. Coated substrates are also provided.

    摘要: The invention provides powder coatings that consistently produce durable finishes when cured, and are stable when uncured. These powder coatings of the invention include novel film forming systems. The novel film forming system, in turn, includes a polymer component and a crosslinker component. In one embodiment, the polymer component is novel; and, in another embodiment, both the polymer and crosslinker components are novel. The novel polymer component includes a novel polyester polyol. This novel polyester polyol includes the reaction product of a cycloaliphatic component and a polyfunctional isocyanurate component. The novel crosslinker component which can be used when practicing certain embodiments of this invention includes a novel, polyfunctional isocyanate compound which is at least partially blocked with at least one of the following: a polyhydroxy aromatic compound, or a mixture of a polyhydroxy aromatic compound and a hydroxy-functional ester compound.
