Abstract
Improved coating compositions which incorporate acrylate resins having multiple carbon-to-carbon bond unsaturation attached to the polymer chain through ester and/or urethane linkage are derived from the reaction product of: PA0 (1) an acrylate resin having multiple epoxide functionality attached to the polymer chain through an ester or ether linkage reacted with an unsaturated carboxylic acid preferably acrylic or methacrylic acid; or PA0 (2) an acrylate resin having multiple hydroxyl group functionality reacted with an organoisocyanate having 0.5 to 1.0 unit of carbon-to-carbon unsaturation per mole of isocyanate. Such coatings are particularly useful in formulating gel coat composites which exhibit hydrolytic stability and good weatherability.
