ABSTRACT:
A water-free, water-free reducible primer composition having a volatile organic content of less than 3 pounds per gallon yields a tough, flexible, and weatherable film when applied to metal or plastic substrates. The base resin is a polyester having an acid number of from about 50 to about 60 and a hydroxyl number of from about 160 to about 200. The polyester is the reaction product of from about 0.45 to about 0.5 mole % of adipic acid, from about 0.35 to about 0.4 mole % of neopentyl glycol, and from about 0.15 to about 0.2 mole % of trimethylolpropane.
