摘要： An automotive refinish coating composition having a volatile organic content not exceeding 3.0 pounds per gallon contains a hydroxyl functional polyester and a polyisocyanate curing agent. The hydroxyl functional polyester is prepared from reactants containing:A. from about 15 percent to about 50 percent of a polyol or mixture of polyols, each having a formula molecular weight from about 50 to about 2,000;B. from about 15 percent to about 50 percent of a long chain monocarboxylic acid or mixture of such acids, each having from about 6 to 24 carbon atoms; andC. from about 15 percent to about 30 percent of 1,4-cyclohexane dicarboxylic acid; the percentages based on the total weight of reactants used in preparing the polyester. The refinish coating composition is particularly suitable as a clear topcoat over a pigmented basecoat.
