INTEGRATED DUAL-CURE COATING MATERIAL SYSTEM AND USE THEREOF FOR THE INTERNAL AND EXTERNAL COATING OF COMPLEX SHAPED THREE-DIMENSIONAL SUBSTRATES

摘要

The invention relates to an integrated dual-cure coating material system, comprising two dual-cure multi-component systems (A) and (B), made from mostly or entirely the same components, each with two layered components separated from each other, whereby (I) one component comprises (i.1) isocyanate reactive functional groups, (i.2) reactive functional groups, containing at least one bond which may be activated by actinic radiation, (i.3) plasticising structural units, with a component of three-dimensional networks which lower the glass transition temperature Tg thereof and/or (i.4) hardening structural units, with a component of three-dimensional networks which increase the glass transition temperature Tg thereof and (II) a component comprising (ii.1) free isocyanate groups, (ii.2) reactive functional groups, containing at least one bond which may be activated by actinic radiation, (ii.3) plasticising structural units, with a component of three-dimensional networks which lower the glass transition temperature Tg thereof and/or (ii.4) hardening structural units, with a component of three-dimensional networks which increase the glass transition temperature Tg thereof and whereby the dual cure coating material system (B) has (a) a lower total content of reactive functional groups with bonds which may be activated by actinic radiation and/or (b) a lower total content of hardening structural units with a component of three-dimensional networks which increase the glass transition temperature Tg thereof, than the dual cure coating material system (A) and use thereof.
