Abstract
This invention provides a linear thermosettable polyester based upon 10-20 weight percent cyclohexanedimethanol, 10-16 weight percent adipic acid, 12-16 weight percent neopentyl glycol, 12-16 weight percent propylene glycol or butanediol, and 40-48 weight percent isophthalic acid component.
Claims8
A linear thermosettable polyester resin based upon 10-20 weight percent cyclohexanedimethanol, 10-16 weight percent adipic acid, 12-16 weight percent neopentyl glycol, 12-16 weight percent propylene glycol or butanediol, and 40-48 weight percent isophthalic acid component.
A coating composition comprising
- (A) a linear thermosettable polyester resin based upon 10-20 weight percent cyclohexanedimethanol, 10-16 weight percent adipic acid, 12-16 weight percent neopentyl glycol, 12-16 weight percent propylene glycol or butanediol, and 40-48 weight percent isophthalic acid component,
- (B) between about 10 weight percent and about 20 weight percent on resin solids of an aminoplast,
- (C) between about 0.1 and about 1 weight percent on resin solids of an acid catalyst, and
- (D) an inert organic solvent in an amount sufficient to provide a solids content of between about 50 weight percent and about 75 weight percent.
