Abstract[English]
The present application is directed to a two component (2K) composition which is snap curable at room temperature, said composition comprising: a first component comprising, based on the weight of said component: from 60 to 100 wt.% of a) at least one epoxy (meth)acrylate compound, said compound having at least one (meth)acrylate group and at least one epoxide group; from 0 to 20 wt.% of b) at least one epoxide compound not having (meth)acrylate functionality; and, from O to 20 wt.% of c) at least one ethylenically unsaturated non-ionic monomer not having epoxide functionality; a second component comprising: d) i) at least one polyamine having at least two amine hydrogen atoms reactive towards epoxide groups; and, d) ii) at least one polythiol, wherein the composition is characterized in that the molar ratio of active hydrogen atoms provided by said second component to the total of epoxide groups and ethylenically unsaturated groups provided by said first component is from 0.75:1 to 1 :1.[French]
La présente demande concerne une composition à deux composants (2K) qui peut durcir instantanément à température ambiante, ladite composition comprenant : un premier composant comprenant, sur la base du poids dudit composant : de 60 à 100 % en poids de a) au moins un composé de (méth)acrylate d'époxyde, ledit composé ayant au moins un groupe (méth)acrylate et au moins un groupe époxyde ; de 0 à 20 % en poids de b) au moins un composé époxyde n'ayant pas de fonctionnalité (méth)acrylate ; et, de 0 à 20 % en poids de c) au moins un monomère non ionique éthyléniquement insaturé n'ayant pas de fonctionnalité époxyde ; un second composant comprenant : d) i) au moins une polyamine comportant au moins deux atomes d'hydrogène amine réactifs vis-à-vis des groupes époxyde ; et,d) ii) au moins un polythiol ; cette composition étant caractérisée en ce que le rapport molaire entre les atomes d'hydrogène actifs fournis par ledit second composant au total des groupes époxyde et les groupes éthyléniquement insaturés fournis par ledit premier composant est de 0,75 : 1 à 1 : 1.
