Claim 9:
10. A two component composition comprising:
(A) a first component comprising:
a) at least one elastomer modified epoxy resin;
b) at least one internally flexibilized epoxy resin which is characterized by a Shore D hardness, as measured with a durometer in accordance with ASTM D2240, of ≤45 when cured with diethylene triamine;
c) at least one chelate modified epoxy resin; and
d) optionally at least one epoxy resin different from said resins a) to c); and,

(B) a second component comprising:
e) a curative which consists of at least one compound possessing at least two epoxide reactive groups per molecule, said curative being characterized by at least one Mannich base, wherein said curative e) consists of:

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.
