Abstract
Provided are various 2-acetylglutarate esters of polyols which are useful as poller crosslinkers for use in thermosetting coating compositions, as well as methods of preparation of these materials. In particular, the invention provides crosslinkers of the formula ##STR1## wherein R and R' are independently t-butyl, t-amyl, or phenyl, and x is an integer of from 2 to 5.
Claims10
A thermosetting coating composition comprising
- (I) about 15 to 80 weight percent of a curable polymer;
- (II) about 0 to 50 weight percent of a solvent;
- and
- (III) about 10 to about 40 weight percent of a crosslinking compound selected from the group consisting of ##STR8## wherein R is t-butyl, t-amyl, or phenyl, and R' is a di- or trifunctional polyol, and x is an integer of from 2 to 5.
