Claim 10:
11. A two component (2K) composition according to claim 1, said composition comprising:
A) a first component comprising, based on the weight of said first component:
from 20 to 80 wt. % of a) at least one elastomer modified epoxy resin;
from 5 to 30 wt. % of b) at least one internally flexibilized epoxy resin;
from 1 to 15 wt. % of c) at least one chelate modified epoxy resin; and
from 0 to 25 wt. % of d) at least one epoxy resin different from said resins a) to c); and,

B) a second component comprising:
e) as a curative (i) at least one compound possessing at least two epoxide reactive groups per molecule, and characterized by comprising at least one Mannich base and (ii) from 90 to 100 mol. % of said Mannich base(s); from 0 to 10 mol. % of secondary epoxide reactive compounds selected from i) polyamines having at least two amine hydrogens reactive toward epoxide groups; and ii) mercapto compounds having at least two mercapto groups reactive toward epoxide groups,

wherein said two component composition is characterized in that the molar ratio of epoxide reactive groups provided in said curative e) to epoxide groups is from 0.95:1 to 1.5:1.
