Claims30
A curable composition comprising
- (i) at least one partially acrylated epoxy monomer or oligomer having a number average molecular weight of between 300 and 10,000 and containing at least one 1,2-epoxide group and at least one terminal acrylate or methacrylate group;
- and
- (ii) an active mono-, di- or polyamine curing agent in an amount at least sufficient to react with substantially all the 1,2-epoxide groups, the acrylate groups and methacrylate groups.
A curable composition comprising
- (i) at least one partially acrylated epoxy monomer or oligomer having a number average molecular weight of between 150 and 10,000 and containing at least one 1,2-epoxide group and at least one terminal acrylate or methacrylate group wherein the partially acrylated epoxy monomer or oligomer is selected from the group consisting of a partially acrylated bisphenol A epoxy resin, a partially acrylated bisphenol F epoxy resin, a partially acrylated epoxy novolac resin, a partially acrylated diglycidyl ether of neopentyl glycol, a partially acrylated diglycidyl ether of alkoxylated neopentyl glycol, a partially acrylated trimethylol propane triglycidyl ether, a partially acrylated alkoxylated trimethylol propane triglycidyl ether, a partially acrylated trimethylol ethane triglycidyl ether and a partially acrylated alkoxylated trimethylol ethane triglycidyl ether;
- and
- (ii) an active mono-, di- or polyamine curing agent in an amount at least sufficient to react with substantially all the 1,2-epoxide groups, the acrylate groups and methacrylate groups.
