Coating compositions with dicarboxylic half ester containing polymers and polyanhydride curing agents |
摘要 |
Coating compositions comprised of (a) a carboxyl functional adduct which is the reaction product of (i) a compound, polymer or oligomer containing pendant and/or terminal hydroxyl or epoxy functional groups and (ii) tartaric acid, malic acid, adipic acid, succinic acid, or anhydrides of said acids; and an anhydride curing agent are disclosed. The coating compositions have accelerated tack-free times and enhanced adhesion to zinc-coated steel and cold rolled steel without the use of a chrome containing wash primer.
