Abstract
Abstract Disclosed is an alkyd composition adapted to be dissolved in a solvent and used as a high solids coating, said alkyd composition being derived from the following components: (A) about 75 to about 85 mole % terephthalic, or phthalic acid, (B) about 15 to about 25 mole % of adipic, sebacic or azelaic acid, (C) about 6 to about 12 mole % of trimethylol ethane or trimethylol propane, (D) about 80 to about 90 mole % neopentyl glycol, and (E) about 4 to about 8 mole % 2,2,4-trimethyl-pentane-1,3-diol.
