Composition curable thermally and with actinic radiation (dual-cure
composition) comprising
A) 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; and
B) 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.
Composição curable tèrmica e com a radiação actinic (duplo-cure a composição) que compreende A) ao menos um constituent que contem na média por a molécula ao menos um grupo preliminar ou secundário do carbamate e ao menos uma ligação que podem ser ativados com radiação actinic e preparable perto do polyfunctional combina conter ao menos dois isocyanate-isocyanate-reactive, grupos funcionais ácido-acid-reactive ou epoxide-epoxide-reactive e monoisocyanates, monoacids ou monoepoxides apropriados ou dos polyisocyanates, os polyacids ou os polyepoxides e compostos apropriados que contêm um grupo funcional isocyanate-isocyanate-reactive, ácido-acid-reactive ou epoxide-epoxide-reactive; e B) ao menos um constituent que contem na média por a molécula ao menos um grupo funcional carbamate-carbamate-reactive e também, onde apropriado, ao menos uma ligação que pode ser ativada com radiação actinic; e seu uso como o adesivo, o composto de sealing e o material do revestimento.
