Abstract
There are provided curable anaerobic pressure sensitive adhesive stocks in the form of sheets and tapes in which the adhesive is contained between two differential release surfaces. This construction permits total pressure sensitive adhesive transfer to a substrate which is to be firmly secured to another substrate upon the exclusion of oxygen and initiation of cure of the anaerobic resin. The adhesive layer provided may be homogeneous or heterogeneous, and there may be contained within the adhesive layer a support layer. The release liner employed is preferably impervious to migration of contained compounds which serve as the accelerators for cure of the curable anaerobic resin.
