Abstract
A binder composition includes 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; a carboxyl-functionalized resin; and a liquid reactive diluent. A combined acid value of the carboxyl-functionalized resin and the liquid reactive diluent is 50 to 500. Uses of the binder composition, for example in composites, coatings, elastomer formulations, and adhesives are also disclosed.
Claims19
A binder composition comprising:
- 5 to 65 weight percent of 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;
- greater than 0 to 65 weight percent of a carboxyl-functionalized resin having an acid value of greater than or equal to 50;
- 5 to 75 weight percent of a liquid reactive diluent;
- and
- 0.1 to 5 weight percent of an initiator;
- wherein a combined acid value of the carboxyl-functionalized resin and the liquid reactive diluent is 50 to 500;
- wherein the carboxyl-functionalized resin comprises a carboxyl-acid functionalized polymer comprising a polyester, an acrylic polymer, or a combination thereof;
- and
- wherein the liquid reactive diluent comprises at least one of:
- a hydroxyl-functionalized C1-12 alkyl (meth)acrylate,
- a (C1-6 alkyl) hydrogen maleate,
