Abstract
There is provided a curable anaerobic pressure sensitive adhesive composition, a mixture of a curable anaerobic system and a high molecular weight polymer system. The mixture which may include a tackifier and other functional additives constitutes a pressure sensitive adhesive and exhibits elastomeric properties. There is also provided in the composition an initiator system necessary to permit curing of the anaerobic pressure sensitive composition upon activation by the exclusion of oxygen. One or more accelerators for cure may also be provided. In one embodiment a component of the catalyst system may be either absent and provided later or latently present in microspheres which upon rupture will enhance the curing operation.
