AI Technical Summary
Technical Problem
Conventional adhesive tapes for house wrap sheets have inadequate UV blocking properties, leading to decreased adhesive force, curling, and mechanical strength degradation due to sunlight exposure, and poor hand-cutting properties.
Method used
An adhesive tape comprising a base material layer of flat yarn cloth with thermoplastic resin films laminated on both surfaces, containing a black pigment in both film layers, and an adhesive layer formed with an acrylic polymer and crosslinking agent, enhancing UV blocking and mechanical properties.
Benefits of technology
The adhesive tape maintains excellent hand-cutting and mechanical properties, resisting curling and maintaining adhesive force even under sunlight exposure, making it suitable for fixing house wrap sheets.
