Abstract:
1. A polyurethane composition consisting of A) 10 to 55% by weight of a polyisocyanate component comprising an exclusively diol-based NCO-terminated polyurethane prepolymer, wherein the NCO groups are bonded in a primary manner, and wherein the prepolymer comprises a residual contents of free monomeric isocyanate of less than 0.5% by weight, B) 15 to 79.989% by weight of an isocyanate-reactive polymer, C) 10 to 70% by weight of a compound having groups which react by polymerizing with an ethylenically unsaturated compound under the action of actinic radiation (radiation-curing groups) wherein the compound is free of NCO groups, D) from 0.001 to 2% by weight of a free-radical stabilizer, E) from 0.01 to 7.5% by weight of a photoinitiator, F) optionally up to 3% by weight of a catalyst, G) optionally up to 50% by weight of assistants and additives.
