Two component epoxy resin composition containing - a K1 epoxy resin component, comprising at least one epoxy resin A with an average of more than one epoxy group per molecule; and - a hardener component K2, comprising between 1-10% by weight, preferably 4-8% by weight, based on the total weight of hardener component, of polyamide terminated in amino groups B; containing at least one of the components K1, K2 at least one impact toughness modifier terminated in amino C1 groups, which is produced by reacting a polyurethane prepolymer having isocyanate groups, a primary diamine, and if necessary at least one Michael acceptor, producing the polyurethane prepolymer having isocyanate groups from at least one polyisocyanate and at least one polyester- or polyether polyol, which has at least two hydroxyl groups, and is part of the hardener component K2, especially in an amount from 1 to 30% by weight, based on the weight of the hardener component K2. |
