Abstract

Adhesive articles such as flexible tapes are described. The adhesive articles include oppositely directed faces of adhesives that are suited for adhesive applications for laminating flooring materials and other construction applications.

First claim

What is claimed is:

1 . An adhesive article comprising:
a carrier defining a first face and a second face, wherein the second face is oppositely directed from the first face; a first adhesive layer at least partially disposed on the first face; a second adhesive layer at least partially disposed on the second face; wherein the adhesive article is at least partially disposed between a flooring material and a subfloor.

2 . The adhesive article of claim 1 , wherein the adhesive of the second adhesive layer is compositionally different than the adhesive of the first adhesive layer.

3 . The adhesive article of claim 1 , wherein the adhesive of the second adhesive layer is compositionally the same as the adhesive of the first adhesive layer.

4 . The adhesive article of claim 1 further comprising:
a release liner at least partially disposed on and at least partially covering at least one of the first adhesive layer and the second adhesive layer.

5 . The adhesive article of claim 1 further comprising:
a first release liner at least partially disposed on the first adhesive layer; and
a second release liner at least partially disposed on the second adhesive layer.

6 . The adhesive article of claim 1 wherein the carrier includes a material selected from the group comprising scrim, nonwoven materials, paper, films, and combinations thereof.

7 . The adhesive article of claim 6 wherein the carrier comprises polyethylene terephthalate (PET).

8 . The adhesive article of claim 1 wherein the first adhesive layer comprises at least one adhesive of acrylic adhesives, rubber-based adhesives, polyurethane-based adhesives, silicone-based adhesives.

9 . The adhesive article of claim 1 wherein the first adhesive layer comprises an emulsion adhesive.

10 . The adhesive article of claim 1 wherein the first adhesive layer has a thickness within a range of from about 6.3 microns to about 203.2 microns.

11 . The adhesive article of claim 10 wherein the first adhesive layer has a thickness within a range of from about 50.8 microns to about 101.6 microns.

12 . The adhesive article of claim 1 wherein the second adhesive layer comprises at least one adhesive of acrylic adhesives, rubber-based adhesives, polyurethane-based adhesives, silicone-based adhesives.

13 . The adhesive article of claim 10 wherein the second adhesive layer comprises a high performance acrylic adhesive.

14 . The adhesive article of claim 1 wherein the second adhesive layer has a thickness within a range of from about 6.3 microns to about 203.2 microns.

15 . The adhesive article of claim 14 wherein the thickness of the second adhesive layer is about 50.8 microns to about 101.6 microns.

16 . The adhesive article of claim 1 wherein the release liner comprises a film material, a paper material, and combinations thereof.

17 . The adhesive article of claim 16 , wherein the film material is polyethylene terephthalate (PET).

18 . The adhesive article of claim 16 , wherein the paper material is heavy basis weight kraft paper.

19 . The adhesive article of claim 1 wherein the adhesive of at least one of the first adhesive layer and the second adhesive layer exhibits a 180 degree peel adhesion within a range of from about 4.5 N/25.4 mm to about 40.1 N/25.4 mm for a 15 minute dwell period.

20 . The adhesive article of claim 19 wherein the adhesive of at least one of the first adhesive layer and the second adhesive layer exhibits a 180 degree peel adhesion within a range of from about 13.3 N/25.4 mm to about 31.1N/25.4 mm for a 15 minute dwell period.

22 . The adhesive article of claim 1 wherein the adhesive of at least one of the first adhesive layer and the second adhesive layer exhibits a 180 degree peel adhesion within a range of from about 8.9 N/25.4 mm to about 44.5 N/25.4 mm for a 24 hour dwell period.

23 . The adhesive article of claim 22 wherein the adhesive of at least one of the first adhesive layer and the second adhesive layer exhibits a 180 degree peel adhesion within a range of from about 15.6 N/25.4 mm to about 31.1N/25.4 mm for a 24 hour dwell period.

24 . The adhesive article of claim 22 wherein the adhesive of at least one of the first adhesive layer and the second adhesive layer exhibits a 180 degree peel adhesion within a range of from about 17.8 N/25.4 mm to about 24.5N/25.4 mm for a 24 hour dwell period.

25 . The adhesive article of claim 1 wherein the adhesive of at least one of the first adhesive layer and the second adhesive layer exhibits a loop tack within a range of from about 2.2 N/25.4 mm to about 35.6 N/25.4 mm.

26 . The adhesive article of claim 25 wherein the adhesive of at least one of the first adhesive layer and the second adhesive layer exhibits a loop tack within a range of from about 13.4 N/25.4 mm to about 31.1 N/25.4 mm.

27 . The adhesive article of claim 1 wherein the adhesive of at least one of the first adhesive layer and the second adhesive layer exhibits a shear within a range of from about 22.2 N/25.4 mm to about 289.1 N/25.4 mm as measured in peak N to failure (645.2 sq. mm).

28 . The adhesive article of claim 27 wherein the adhesive of at least one of the first adhesive layer and the second adhesive layer exhibits a shear within a range of from about 44.5 N/25.4 mm to about 111.2 N/25.4 mm as measured in peak N to failure (645.2 sq. mm).

29 . The adhesive article of claim 1 wherein at least one of the first adhesive layer and the second adhesive layer includes at least a layer portion that is patterned.

30 . The adhesive article of claim 1 wherein the adhesive article is an adhesive tape.

31 . The adhesive article of claim 30 wherein the adhesive tape is in roll form.
