摘要： The present invention relates to a substrate having (a) a first material applied to at least a portion of the substrate, and (b) a coating layer deposited from a powder coating composition including a film-forming resin, and optionally a crosslinker that is reactive with the film-forming resin, in direct contact with at least a portion of the substrate to which the first material has been applied. The first material is (i) a catalyst that catalyzes cure of the powder coating composition, (ii) a component reactive with the film-forming resin and/or the crosslinker of the powder coating composition, and/or (iii) a rheology modifier.

摘要： The present invention relates to a powder coating composition for preparing a dielectric coating. The powder coating composition includes: (a) an epoxy functional polymer; (b) a poly-carboxylic acid functional polyester polymer reactive with the epoxy functional polymer and which has an acid value of less than 100 mg KOH/g; and (c) a poly-carboxylic acid functional (meth)acrylate polymer reactive with the epoxy functional polymer. Further, if a colorant is present, the powder coating composition comprises 35 weight % or less of the colorant, based on the total solids weight of the coating composition.
