Claims21
An activatable material comprising:
- i) at least two different epoxy/elastomer adducts;
- ii) an epoxy/diacid adduct present in an amount of from about 0.05% to about 20% by weight of the material;
- iii) a silane-modified epoxy resin;
- iv) a phenol-terminated urethane-based toughening agent;
- and
- v) a calcium-based reinforcement component;
- wherein a ratio of the at least two different epoxy/elastomer adducts to the epoxy/diacid adduct is about 3 parts of the at least two different epoxy/elastomer adducts to about 1 part of the epoxy/diacid adduct.
