Two component (2k) composition based on epoxy (meth)acrylate resin

Abstract

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 0 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.
