ABSTRACT:
The invention relates to urethane prepolymers, obtainable by reaction of:(A) 15 to 85 wt.-% of one or more α,ω-terminated poly(meth)acrylate diols,(B) 0 to 30 wt.-% of one or more radically curable, polyhydroxy-functional compounds,(C) 14 to 60 wt.-% of one or more polyisocyanates,(D) 1 to 40 wt.-% of a monofunctional compound, reactive vis-à-vis isocyanate groups, which also contains one or more radically curable grouping,as well as their use.
