Abstract

A method of assembling a structure comprises applying an epoxy composition to at least one of a first member and a second member, sandwiching the epoxy composition between the first and second members, and bonding the two members wherein the adhesive bond is a thermally cured mass. The epoxy composition contains an epoxy resin, a phenolic or amine compound as a chain extender, a basic catalyst and a polymeric toughener. The composition can be formulated in two parts wherein part A contains the catalyst and part B has the epoxy resin.
