ABSTRACT:
A composite pressure sensitive adhesive construction contains a central release liner, a layer of an adhesive on each side thereof, and optionally, an exterior release liner on at least one of the adhesive layers. The central release liner and the exterior release liner contain release coatings on surfaces thereof which contact the adhesive layer. The pressure sensitive adhesive construction may be utilized in sealing pipe insulating jackets wherein the exterior release liners are removed and the adhesive construction is applied to the opposite longitudinal ends or sides of the insulating jacket cover. The insulating jacket may then be stored until utilized whereupon the central release liner is removed, the jacket inserted about the pipe, and a sealing connection then made by pressing the two exposed adhesive layers together.
