Liquid binder compositions and uses thereof

A binder composition comprising:

• 5 to 75 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;
• 5 to 75 weight percent of a liquid reactive diluent;
• and
• 0 to 5 weight percent of an initiator;
• wherein weight percent of each component is based on the total weight of the binder composition;
• wherein the liquid reactive diluent has a total acid value of 50 to 432 and comprises at least one of:
• a (C1-8 hydrocarbyl) hydrogen maleate,
• a bis(C1-8 hydrocarbyl) maleate,
• an adduct of an anhydride and an epoxidized fatty acid methyl ester,
• an anhydride that is at least partially esterified with a C1-8 alcohol, a hydroxy-functionalized vinyl ester, dicyclopentadiene, an alkyl glycidyl ether, a fatty acid ester of an epoxidized oil or a combination thereof, or
• a transesterification reaction product of an epoxidized fatty acid methyl ester and a vinyl compound having pendant hydroxyl groups, said transesterification product having a number average molecular weight of 650 grams per mole or less,
• or a combination thereof;
• and
• optionally wherein the composition further comprises up to 40 weight percent a vinyl monomer, a hydroxyl-functionalized C1-12 alkyl (meth)acrylate, or a combination thereof.
