Abstract
Two pieces (12 and 14) of material are releasably bonded together with a thermoplastic adhesive (28) in which a heating element (30) is embedded. After application, the adhesive (28) cures at ambient temperature or at a low elevated temperature produced by passing an electrical current through the heating element (30), to bond the pieces (12 and 14) together. The pieces (12 and 14) are debonded or separated by passing a relatively high electrical power through the heating element (30), to soften or melt the adhesive (28). A preferred adhesive (28) is a cyanoacrylate.
