Abstract:
1. A method of forming a corrosion resistant adhesive bond between facing panel surfaces of different compositions where the composition of at least one of the surfaces is susceptible to corrosion; the method comprising: applying a curable adhesive composition to a bonding region of at least one of the panel surfaces, the adhesive composition comprising microcapsules of a corrosion inhibiting composition for at least one of the surface compositions, the curable adhesive composition further comprising spacer beads for maintaining an interfacial gap between the facing surfaces until the adhesive is cured; placing the facing surfaces together to form an adhesive interface; promoting curing of the adhesive and at a predetermined time after the facing surfaces have been placed together promoting release of the corrosion inhibiting composition from microcapsules for corrosion inhibiting contact over the adhesive bonding region with at least one of the facing panel surfaces, the release of the corrosion inhibiting composition from at least some of the microcapsules being promoted before the adhesive is cured.
