Abstract

A two-component composition, component K1, including at least one (meth)acrylate monomer, at least one elastomer having (meth)acrylate end groups, at least one additive selected from the group consisting of activator for free-radical curing, inhibitor for free-radical curing, filler and adhesion promoter; and a component K2 including at least one initiator for free-radical curing wherein the elastomer is a polyurethane (meth)acrylate produced from the reaction of at least one diol including at least one dimer fatty acid-based polyester diol with at least one diisocyanate and a (meth)acrylic acid, a (meth)acrylamide or a (meth)acrylate ester having a hydroxyl group, wherein the at least one diol initially reacts with the diisocyanate which is present in stoichiometric excess and the resulting isocyanate-terminated polyurethane is subsequently reacted with the (meth)acrylic acid, the (meth)acrylamide or the (meth)acrylate ester having a hydroxyl group to afford the elastomer.
