Abstract

Composition curable thermally and with actinic radiation (dual-cure composition) comprisingA) at least one constituent containing on average per molecule at least one primary or secondary carbamate group and at least one bond which can be activated with actinic radiation and preparable by from polyfunctional compounds containing at least two isocyanate-reactive, acid-reactive or epoxide-reactive functional groups and suitable monoisocyanates, monoacids or monoepoxides or from polyisocyanates, polyacids or polyepoxides and suitable compounds which contain an isocyanate-reactive, acid-reactive or epoxide-reactive functional group; andB) at least one constituent containing on average per molecule at least one carbamate-reactive functional group and also, where appropriate, at least one bond which can be activated with actinic radiation;and its use as adhesive, sealing compound and coating material.
