Abstract

An adhesive article adapted to attach structures to a substrate and a method of using the same. The adhesive article has a failure mode that minimizes damage to the substrate surface. The adhesive article comprises an adhesive layer having a first adhesive region and a second adhesive region. The first adhesive region is adapted to attach a top portion of the structure to the substrate. The second adhesive region is adapted to attach a bottom portion of the structure to the substrate. The second adhesive region comprises reduced adhesive properties.

Claims

1. An adhesive article adapted to attach structures to a substrate, said article comprising a stretch releasing adhesive tape having an adhesive layer with a first adhesive region adapted to attach a top portion of the structure to the substrate and a second adhesive region with reduced adhesive properties adapted to attach a bottom portion of the structure to the substrate, the stretch releasing adhesive tape including a pull tab adjacent to the second adhesive region.

2. The adhesive article of claim 1 wherein the stretch releasing adhesive tape comprises a multi-layer structure.

3. The adhesive article of claim 1 wherein the stretch releasing adhesive tape comprises a backing layer selected from one of a film, an elastic foam, and an inelastic foam.

4. The adhesive article of claim 1 wherein the stretch releasing adhesive tape is selected from the group consisting of a pressure sensitive adhesive tape with an elastic structural member, a pressure sensitive adhesive tape with a highly extensible and substantially inelastic structural member, or a solid pressure sensitive adhesive.

5. The adhesive article of claim 1 wherein the adhesive layer comprises more than two adhesive regions.

6. The adhesive article of claim 1 wherein the adhesive layer comprises a plurality of adhesive regions with progressively reduced adhesive properties.

7. The adhesive article of claim 1 wherein the adhesive layer comprises progressively reduced adhesive properties.

8. The adhesive article of claim 1 wherein the second adhesive region comprises a surface area less than a surface area of the first adhesive region.

9. The adhesive article of claim 1 wherein the second adhesive region comprises a surface area greater than or equal to about 22% of a surface area of the adhesive layer.

10. The adhesive article of claim 1 wherein the second adhesive region is provided with a material selected from the group consisting of release liner material, repositionable pressure sensitive adhesive, polymeric film, paper, powder, scrims, nonwoven fabric, ink, and low adhesion backsize material.

11. The adhesive article of claim 1 comprising a two-sided adhesive tape article.
