摘要： An integrated dual-cure coating material system which comprises two dual-cure multicomponent systems (A) and (B) which are composed predominantly or wholly of the same constituents and comprise in each case two components stored separately from one another,(I) one component containing (i.1) isocyanate-reactive functional groups and (i.2) reactive functional groups containing at least one bond which can be activated with actinic radiation, (i.3) flexibilizing structural units which as parts of three-dimensional networks lower their glass transition temperature Tg, and/or (i.4) hardening structural units which as part of three-dimensional networks raise their glass transition temperature Tg and (I1) one component containing (ii.1) free isocyanate groups, (ii.2) reactive functional groups containing at least one bond which can be activated with actinic radiation and (ii.3) flexibilizing structural units which as parts of three-dimensional networks lower their glass transition temperature Tg, and/or (ii.4) hardening structural units which as part of three-dimensional networks raise their glass transition temperature Tg, the dual-cure coating material system (B) having (a) overall a lower quantity of reactive functional groups containing bonds which can be activated with actinic radiation, and/or (b) overall a higher quantity of hardening structural units which as part of three-dimensional networks raise their glass transition temperature Tg, than the dual-cure coating material system (A); and its use.
