Abstract:
1. A composition comprising: (a) 15 to 60 wt.-% fillers, (b) 3 to 35 wt.-% of at least one mono- or polyethylenically unsaturated compound which is not a urethane (meth)acrylate and has a molecular weight between 300 and 5,000 g/mol, (c) 0.1 to 5 wt.-% of at least one initiator system which is capable of starting a radical reaction, (d) 1 to 40 wt.-% plasticizers, (e) 0 to 10 wt.-% auxiliaries, and (f) 30 to 81.9 wt.-% of at least two urethane (meth)acrylates with different molecular weights, a high molecular weight urethane (meth)acrylate having a molecular weight between 1,000 and 20,000 g/mol and a low molecular weight urethane (meth)acrylate having a molecular weight between 300 and 1,000 g/mol, being present in a molecular weight ratio of 1.5:1 to 50:1.
