Abstract
A composition is provided and includes an unsaturated (meth)acrylate polymer or oligomer, an allophanate unsaturated urethane (meth)acrylate, a lactone-containing (meth)acrylate, a first reactive diluent, an adhesion promoter, a second reactive diluent, a light stabilizer, and a photoinitiator.
Claims20
A composition comprising:
- an unsaturated (meth)acrylate polymer or oligomer in an amount of about 25 to about 45 percent by weight, the unsaturated (meth)acrylate polymer or oligomer is a reaction product of a first composition having:
- an organic polyisocyanate;
- a polyol having a number average molecular weight of about 600 to about 4000 g/mol;
- and
- at least one of:
- (1) a hydroxyl-functional (meth)acrylate and (2) an unsaturated (meth)acrylate polyol based on a polyester, a polyether, a polythioether, a polyacetal, a polycarbonate, a dimer fatty alcohol and/or an esteramide, in each case with a number average molecular weight of 400 to 8000 g/mol, at an isocyanate to hydroxyl equivalent ratio of from 0.5:1 to 1:0.5;
- an allophanate unsaturated urethane (meth)acrylate in an amount of about 5 to about 25 percent by weight;
- a lactone-containing (meth)acrylate in an amount of about 2 to about 12 percent by weight;
- a first reactive diluent in an amount of about 15 to about 50 percent by weight, the first reactive diluent having a monomer;
- a surfactant in an amount up to about 0.3 percent by weight;
- an adhesion promoter in an amount of about 1 to about 5 percent by weight;
- a second reactive diluent in an amount of about 1 to about 5 percent by weight, the reactive diluent having a phosphoric acid ester;
- a light stabilizer in an amount of about 0.5 to about 2 percent by weight;
- and
- a photoinitiator in an amount of about 0.5 to about 15 percent by weight.
