Claims35
An epoxy composition comprising:
- (a) an effective amount of a chain extender;
- (b) an effective amount of a catalyst;
- (c) an effective amount of a reactive epoxy resin;
- and
- (d) an effective amount of a polymeric toughener,
- wherein the chain extender, the reactive epoxy resin, the catalyst and the toughener are each in an amount and of a type that are effective, when mixed together, to form a thermally curable adhesive and, when the adhesive is cured, at least about 50% by weight of the epoxy resin is chain extended.
