Abstract[English]
A two-component (2K) curable composition comprising: a first component comprising: a) at least one compound having at least two (meth)acrylate groups and having a weight average molecular weight (Mw) of at most 600 Daltons; and, optionally b) at least one ethylenically unsaturated compound which is distinct from said compound(s) of a); and, a second component comprising: c) at least one compound having at least one primary amine group, wherein the two-component (2K) composition further comprises: d) a rheology control agent comprising electrically non-conductive fillers, electrically conductive fillers or mixtures thereof; and, further wherein the two-component (2K) composition is characterized in that the molar ratio of (meth)acrylate groups to primary amine groups is from 3:1 to 1:1.[French]
L'invention concerne une composition durcissable à deux composants (2K) comprenant : un premier composant comprenant : a) au moins un composé ayant au moins deux groupes (méth)acrylate et ayant un poids moléculaire moyen en poids (Mw) d'au plus 600 daltons ; et, éventuellement b) au moins un composé éthyléniquement insaturé qui est distinct dudit ou desdits composés de a) ; et, un second composant comprenant : c) au moins un composé ayant au moins un groupe amine primaire, la composition à deux composants (2K) comprenant en outre : d) un agent de régulation de rhéologie comprenant des charges électriquement non conductrices, des charges électriquement conductrices ou des mélanges de ceux-ci ; et, en outre, la composition à deux composants (2K) étant caractérisée en ce que le rapport molaire des groupes (méth)acrylate aux groupes amine primaire est de 3 : 1 à 1 : 1.
