Kind Code:
A1
Abstract:
Two component (2K) composition comprises: (I) a first component comprising: a) at least one epoxy silane oligomer according to Formula (AI) wherein: R e is a C 1-C 6 alkyl group; R f is an epoxide substituted C 1-C 12 alkyl group, C 3-C 18 cycloalkyl group or C 2-C 18 alkoxyalkyl group; R g is H or a C 1-C 6 alkyl group; R h is a C 1-C 6 alkyl group; i is an integer ≥ 1; and, j is an integer ≥ 1; b) at least one polyepoxide compound having at least three epoxide groups per molecule; and, optionally c) at least one compound selected from the group consisting of monoepoxide compounds and diepoxide compounds; wherein the compounds of part b) and part c) do not meet Formula (AI); (II) a second component comprising: d) a curative consisting of at least two compounds possessing at least two epoxide reactive groups per molecule, said curative being characterized by comprising: at least one Mannich base; and, at least one cycloaliphatic amine, wherein the two component (2K) composition further comprises: e) core shell rubber particles; and, wherein the two component (2K) composition is further characterized by a molar ratio of epoxide-reactive groups to epoxide groups of from 0.95: 1 to 1.5: 1. Said compositon is curable at room temperature, and demonstrates favorable adhesive strength at both room temperature and under elevated temperature conditions. And the cured reaction product of said compositon can be used as a coating, adhesive or sealant.
