Abstract
The curable coating compositions of the invention comprise a particulate component having at least one binder component (a) which is a solid at 75° F./24° C., and an additive component (b). The curable coating compositions further comprise a crosslinking component (c) reactive with the at least one binder component (a). Additive component (b) has from 12 to 72 carbon atoms, is substantially free of any heteroatoms, is not a crystalline solid at 75° F./24° C. and comprises a mixture of two or more structures selected from the group consisting of aliphatic structures for additive component (b), aromatic-containing structures for additive component (b), cycloaliphatic-containing structures for additive component (b), and mixtures thereof, wherein at least one of the two or more structures is either a cycloaliphatic-containing structure or an aromatic-containing structure. The curable coating compositions are useful as powder coating compositions and powder slurry coating compositions having improved application and/or performance properties.
