Patent ID: 8716429

Claim:
A curable coil coating composition comprising a mixture of: (a) a curable polyester that is a liquid at room temperature, (b) a cross-linking agent; and (c) a solvent; wherein the number average molecular weight of the polyester is from about 2,500 to about 7,500, wherein the hydroxyl number of the polyester is from about 10 to about 100 mg KOH/g, wherein the Tg of the polyester is from 0 to 100° C., wherein the polyester comprises, in polymerized form, a diol mixture consisting essentially of 1,3- and 1,4-cyclohexane dimethanol wherein the molar ratio of the 1,3 isomer to the 1,4 isomer is from about 60:40 to about 5:95, wherein the composition is substantially free of a reactive diluent comprising 1,3- and 1,4-cyclohexane dimethanol, and wherein a cured coating comprising the composition in cured form can have a pencil hardness of at least 2H and a T bend value of 0T.
