摘要: The present invention is directed to curable film-forming compositions and coating kits, each comprising: (a) a polyepoxide functional polymer; (b) a polythiol functional compound, wherein the polythiol functional compound comprises at least two or at least three thiol functional groups and wherein if the polythiol functional compound contains hydroxyl functional groups, the ratio of thiol functional groups to hydroxyl functional groups within the polythiol functional compound is not 1:1; (c) a reactive compound different from the polythiol functional compound (b), containing multiple pendant and/or terminal functional groups selected from carboxylic acid, anhydride, amine and phenol that are reactive with epoxide functional groups; and (d) a pigment. The curable film-forming composition demonstrates a pigment to binder ratio greater than or equal to 2 and less than 3, adhesion to diverse substrates, and fast sandability. The present invention is further directed to coated articles and methods of forming them.

摘要: A coating composition includes: (a) an acid functional polyol polymer having an acid value of greater than 9 mg KOH/g and less than 60 mg KOH/g, and a hydroxyl value of from 100 to 300 mg KOH/g; (b) a non-aminoplast derived crosslinker reactive with the acid functional polyol polymer; and (c) a non-aqueous liquid medium. Further, an equivalent ratio of functional groups on the crosslinker reactive with hydroxyl functional groups to hydroxyl functional groups on the acid functional polyol polymer is within a range of from 0.5 to 1.5. The coating composition is substantially free of an external catalyst. The coating composition cures at a temperature of less than 80° C.
