Film-forming coating compositions are disclosed. The composition comprises a) an epoxy-containing polymer system; and b) a polyacid curing agent comprising two acid functional groups per molecule; wherein the epoxy-containing polymer system comprises: (i) an epoxy resin comprising at least two epoxy functional groups per molecule and which is different from (ii); and (ii) an epoxy functional silsesquioxane. Also disclosed are processes for applying the film-forming composition to a basecoat, and substrates coated in part by a coating deposited from the film-forming compositions.

Low-cure powder coating compositions are disclosed. The compositions comprise a polyepoxide and a material having the structure wherein R1 is an organic radical having 6 to 25 carbon atoms; R2 is an organic radical having 1 to 20 carbon atoms; R3 and R4 are independently alkyl or phenyl groups having 1 to 8 carbon atoms; Z is oxygen or nitrogen, and when Z is oxygen R5 is absent and when Z is nitrogen R5 is hydrogen or is and n is 1 to 4. The material can optionally be reacted with an acidic hydrogen-containing compound. The compositions are curable without the use of crosslinking agents or accelerators. Methods for coating a substrate using these compositions, and substrates coated thereby, are also disclosed, as are additional catalysts useful for the same purpose.
