ANAEROBIC PRESSURE SENSITIVE ADHESIVE

摘要

A structural adhesive is formed by applying an adhesive composition to a substrate, partially curing the adhesive to a pressure sensitive adhesive, and subsequently curing the adhesive by exposing the adhesive to an anaerobic accelerator in the absence of oxygen. The pressure sensitive adhesive provides a tacky surface allowing a temporary bond at room temperature. Upon curing of the adhesive construction, the bond properties change to that of a structural adhesive, providing a strong permanent bond.
