Beschreibung
Zusammenfassung:	A resin comprises: A) a multifunctional (meth)acrylate; B) an NCO-functional polyurethane; C) a radical starter and D) a catalyst. The multifunctional (meth)acrylate A) has a viscosity at 23° C. as determined according to DIN EN ISO 2884-1 of ≤10000 mPa·s, the NCO-functional polyurethane B) has an average NCO group functionality of ≥2 and an equivalent molecular weight with respect to NCO groups of >300 g/mol. The resin is free from isocyanate trimerization catalysts and the resin is free from NCO-reactive compounds or, if NCO-reactive compounds are present in the resin, the molar ratio of NCO groups to NCO-reactive groups is ≥5:1.
