ABSTRACT:
An adhesive system is described as including an adhesive having dispersed metal particles whose function it is to emit heat for the purposes of breaking the bond formed by the adhesive when such action is desired. Specifically, metal particles are embedded within a suitable adhesive material which loses strength at a predetermined, relatively low temperature. When it is desired to break the bond formed by the adhesive, the metal-filled adhesive is placed in a rapidly varying magnetic or electromagnetic field so that the metallic inclusions transfer heat to the adhesive material, thereby raising it to a level which will break the bond formed thereby.
