Abstract
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.
