Abstract
An adhesive system for forming reversible adhesive bonds includes at least one polymeric adhesive component comprising at least one of polyurethanes, polyureas, or epoxy resins and at least one additional component that includes a functional group that can be activated by the introduction of energy, such that a chemical reaction with the adhesive component takes place involving a partial breakdown of the adhesive component. Reversible bonding of articles and controlled parting of an adhesive bond between articles can be achieved with the adhesive system.
