Abstract
The present disclosure is directed to an one-component (1K) curable composition comprising, based on the weight of the composition: from 50 to 90 wt. % of a) at least one epoxy resin which has been modified with a hydrophobic elastomer, said modified epoxy resin having an epoxide equivalent weight of from 200 to 1000 g/eq; up to 15 wt. % of b) at least one epoxy resin distinct from the modified resin of part a); c) at least one compound which provides at least two amine hydrogens reactive toward epoxide groups; and, from 0.01 to 5 wt. % of d) at least one accelerator, wherein the composition is characterized by a molar ratio of epoxide groups to epoxide-reactive groups of from 0.5:1 to 1.4:1.

An one component (1K) curable composition comprising, based on the weight of the composition:
- from 50 to 90 wt. % of a) at least one epoxy resin which has been modified with a hydrophobic elastomer, said modified epoxy resin having an epoxide equivalent weight of from 200 to 1000 g/eq;
- up to 15 wt. % of b) at least one epoxy resin distinct from the modified resin of part a);
- c) at least one compound which provides at least two amine hydrogens reactive toward epoxide groups;
- and,
- from 0.01 to 5 wt. % of d) at least one accelerator,
- wherein the composition is characterized by a molar ratio of epoxide groups to epoxide-reactive groups of from 0.5:1 to 1.4:1.
