The invention relates to compositions that contain: (a) 14 to 55 % by weight of fillers, (b) 3 to 35 % by weight of at least one mono- or poly-ethylenically unsaturated compound that is not urethane (meth)acrylate, (c) 0.1 to 5 % by weight of at least one initiator system that is capable of triggering a radical reaction, (d) 1 to 40 % by weight of a softening agent, (e) 0 to 10 % by weight of adjuvants, such as colorants, pigments, stabilizers, solvents, rheological additives such as flow enhancers and/or retarders, and (f) 30 to 82.9 % by weight of at least two urethane (meth)acrylates of different molecular weight, the molecular weight ratio being in the range of from 1.5: 1 to 50: 1.
