Claim 18:
19. A binder composition comprising:
an epoxidized vegetable oil or a derivative thereof having an epoxy group content of 1 to 12 weight percent, based on the total weight of the epoxidized vegetable oil, and wherein the epoxidized vegetable oil comprises a fatty acid ester comprising C5-26 alkyl groups;
a carboxyl-functionalized resin having an acid value of greater than or equal to 50; and
a liquid reactive diluent;
wherein a combined acid value of the carboxyl-functionalized resin and the liquid reactive diluent is 50 to 500, and
wherein the binder composition further comprises an oligomer formed from reaction of an isocyanate or isocyanate-terminated prepolymer with a vinyl compound having pendent hydroxyl groups; wherein the oligomer and the liquid reactive diluent are provided to the composition in the form of a concentrate comprising 60 to 95 weight percent of the liquid reactive diluent and 5 to 40 weight percent of the oligomer, based on the total weight of the concentrate.
