Abstract
The present invention provides polyester/vinyl dioxolane based coating compositions containing no or essentially no volatile organic components. Oligomers for forming the coating compositions of the present invention are vinyl dioxolane end-capped polyester oligomers.
Claims23
A polyester coating composition containing essentially no volatile organic components, the composition comprising:
- (a) at least one prepolymer which comprises the reaction product of
- (i) at least one substituted vinyl dioxolane monomer having the formula ##STR8## wherein R.sub.1 and R.sub.1 ' are independently hydrogen or an alkyl group having from 1 to 10 carbon atoms, n is a number from 0 to about 10, and R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are independently hydrogen or an alkyl group having irom 1 to about 10 carbon atoms;
- and
- (ii) at least one ester of a polycarboxylic acid;
- and
- (b) a catalyst system comprising cobalt and aluminum and excluding zinc to initiate polymerization of the prepolymer of step (a) to form a coating.
