Abstract

There are provided rolls comprising an air and water barrier article having opposing first and second major surfaces, a pressure sensitive adhesive disposed on at least the first major surface of the article, and a liner having a first major surface that contacts the opposing second major surface of the article, and at least two adhesion modifying zones disposed between the second major surface of the article and the first major surface of the liner, wherein both of a first and second adhesion modifying zones contact the first major surface of the liner, and wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll. There are also provided films made using these air and water barrier articles and building envelopes made using such films.

First claim

What is claimed is:

1. A roll comprising an air and water barrier article having opposing first and second major surfaces, a pressure sensitive adhesive disposed on at least the first major surface of the air and water barrier article, a liner having a first major surface, and at least two adhesion modifying zones disposed between the second major surface of the air and water barrier article and the first major surface of the liner, wherein both of a first adhesion modifying zone and a second adhesion modifying zone contact the first major surface of the liner, and wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll.

2. The roll of claim 1 , wherein a release strength between the second major surface of the liner and the pressure sensitive adhesive is less than or equal to a release strength between the first major surface of the liner and the second major surface of the air and water barrier article.

3. The roll of claim 2 , wherein the air and water barrier article comprises a porous layer at least partially impregnated with a polymeric material wherein a first major surface of the porous layer is covered with the polymeric material.

4. The roll of claim 2 , wherein the air and water barrier article comprises a porous layer at least partially impregnated and encapsulated with a polymeric material.

5. The roll of claim 1 , wherein the liner is coated on at least one of the first major surface or the second major surface with a release coating.

6. The roll of claim 1 , wherein a ratio of a width of the first adhesion modifying zone in a cross direction to a width of the second adhesion modifying zone in the cross direction is at least 3:1.

7. The roll of claim 1 , wherein a width of the air and water barrier article is greater than or equal to 18 inches.

8. The roll of claim 1 , wherein a width of the air and water barrier article is greater than or equal to 4 inches.

9. The roll of claim 1 wherein a ratio of a release force of the first adhesion modifying zone from the liner to a release force of the second adhesion modifying zone from the liner is at least 1:13.

10. The roll of claim 1 , wherein the liner comprises a film selected from at least one of polyester film, paper, polyethylene film, polypropylene film, or polyethylene-coated polymer film, wherein the film is coated on at least one major surface with a release coating.

11. The roll of claim 1 wherein the liner is derived from applying a layer comprising a (meth)acrylate-functional siloxane to a major surface of a substrate; and irradiating said layer, in a substantially inert atmosphere comprising no greater than 500 ppm oxygen, with a short wavelength polychromatic ultraviolet light source having at least one peak intensity at a wavelength of from about 160 nanometers to about 240 nanometers to at least partially cure the layer, optionally wherein the layer is at a curing temperature greater than 25° C.

12. The roll of claim 1 , wherein the air and water barrier article, after removal of the liner, passes Modified Test 1 of ASTM D-1970/D-1970M-13, Modified Test 2 of ASTM D-1970/D-1970M-13, or Modified Test 3 of ASTM D-1970/D-1970M-14.

13. The roll of claim 1 , wherein the air and water barrier article, after removal of the liner, is water vapor permeable.

14. The roll of claim 1 , wherein the air and water barrier article comprises a porous layer at least partially impregnated with a polymeric material wherein a first major surface of the porous layer is covered with the polymeric material.

15. The roll of claim 1 , wherein the air and water barrier article comprises a porous layer at least partially impregnated and encapsulated with a polymeric material.

16. The roll of claim 1 , wherein the air and water barrier article comprises a major surface of a porous layer that is coated with a polymeric material.

17. An air and water barrier film derived from the roll of claim 1 , the air and water barrier film comprising the air and water barrier article, the pressure sensitive adhesive, and the at least two adhesion modifying zones.

18. The air and water barrier film of claim 17 , wherein the pressure sensitive adhesive is adhered to a major surface of a building component.

19. The air and water barrier film of claim 17 , wherein the air and water barrier film passes Modified Test 1 of ASTM D-1970/D-1970M-13, Modified Test 2 of ASTM D-1970/D-1970M-13, or Modified Test 3 of ASTM D-1970/D-1970M-14.
