Abstract
Disclosed are solvent borne thermosetting coating compositions containing curable, aliphatic polyesters, acrylic copolymers, crosslinkers, and nonaqueous solvents. The aliphatic polyesters contain 2,2,4,4-tetramethyl-1,3-cyclobutanediol. Blends of acrylic copolymers with these aliphatic polyesters exhibit good compatibility, viscosity reduction, and good Tg retention. Coating compositions formulated from these blends exhibit high gloss, hardness with flexibility; solvent and chemical resistance; and outdoor durability.
