ABSTRACT:
A method for adhering surfaces together using fast curing epoxy resin compositions is provided. The method includes the steps of mixing together (a) a curable glycidyl ether epoxide group-containing compound, (b) an amino-terminated aliphatic polyether curing agent, (c) a polymeric toughening agent having both a rubbery phase and a thermoplastic phase or being capable of forming, with the epoxide group-containing material, both a rubbery phase and a thermoset phase on curing, and (d) a metal salt catalyst capble of providing an exotherm of at least 20.degree. C.; applying the resulting mixture to a portion of at least one surface; contacting the surface having the mixture applied thereto to a second surface in bonding relationship with the mixture disposed between the surfaces; and curing the mixture.
