摘要：

A sandwich type composite adhesive construction in a simpler form, composed of a central release liner having a permanent adhesive layer on one side thereof and a pressure sensitive adhesive layer on the other side preferably separated therefrom by a release coat or member, and at least one release member on said adhesive layers but in a more complex form containing additional carrier layers or strengthening members including at least one or more support layers between two layers of permanent pressure sensitive adhesive. This adhesive construction provides a product, such as a pipe insulation that has unique properties and is cost effective.This strip-type composite adhesive construction can be made by applying a barrier layer coat to one or more surfaces of the insulation, either to the surfaces of the slit, or to the peripheral surfaces of the insulation adjacent the slit, or to portions of the adjacent surfaces of the insulation adjacent to the slit, or to the entire exterior surface, depending upon the needs of the user.
