Patent ID: 7901532

Claim:
A method of bonding and debonding two or more surfaces or supports or layers of an adhesive system, the method comprising: (i) providing a first power level of thermal radiation and/or thermal conduction and/or thermal energy which passes through an adhesive composition comprising: (a) an adhesive agent, (b) a cleaner, (c) a primer, (d) a first set of thermoexpandable microspheres associated with curing and bonding, and (e) a second set of thermoexpandable microspheres associated with debonding, wherein said second set of thermoexpandable microspheres comprises microspheres encapsulating an expanding agent, said microspheres encapsulating an expanding agent comprising about 3-5%, by weight, of the cleaner and about 5-10%, by weight, of the primer, such that the contents of the first set of thermoexpandable microspheres leach or migrate through the porous shells of the first set of thermoexpandable microspheres into the matrix of the adhesive composition, thereby curing the adhesive composition; and (ii) providing a second power level of thermal radiation and/or thermal conduction and/or thermal energy which concentrates on the surfaces or supports or layers of the adhesive system so as to expand the second set of thermoexpandable microspheres, thereby weakening the adhesive forces in the interface of the adhesive system.
