Dual-cure multi-component system, e.g. for painting cars, comprises a polyisocyanate component and a mixture containing compounds with isocyanate-reactive groups and light-activatable bonds

摘要

A heat- and light-curable (dual-cure) multi-component system with polyisocyanate-containing component(s) (B) also contains component(s) (A) comprising (A1) component(s) with at least 1.8 meq/g isocyanate-reactive functional groups and (A2) component(s) with at least 1.8 meq/g isocyanate-reactive groups plus functional group(s) with light-activatable bond(s).
