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, wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll. There are also provided self adhering air and water barrier articles and building envelopes made using the presently disclosed rolls.

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; and
a liner comprising a substrate and having a first major surface that contacts the opposing second major surface of the air and water barrier article, wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll,
wherein the air and water barrier article comprises a porous layer having a major surface that is coated with a polymeric material, wherein the polymeric material comprises a polyoxyalkylene polymer having at least one end group derived from an alkoxy silane.

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 1 , wherein the liner is coated on at least one of its first or second major surfaces with a release coating.

4. The roll of claim 1 , further comprising surface modification at the interface between the second major surface of the air and water barrier article and the first major surface of the liner.

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

6. The roll of claim 1 , wherein the substrate comprises at least one of polyester film, paper, or polyethylene film, wherein the substrate is coated on at least one major surface with a release coating.

7. 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 the 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 cured at a curing temperature greater than 25° C.

8. The roll of claim 1 , wherein the air and water barrier article passes at least one of 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-13.

9. The roll of claim 1 , wherein the air and water barrier article is water vapor permeable.

10. The roll of claim 1 , wherein the porous layer is at least partially impregnated with the polymeric material, and wherein the major surface of the porous layer is covered with the polymeric material.

11. The roll claim 1 , wherein the porous layer is at least partially impregnated and encapsulated with the polymeric material.

12. The roll of claim 1 , wherein the pressure sensitive adhesive comprises a first pressure sensitive adhesive that is pattern coated on the first major surface of the air and water barrier article.

13. The roll of claim 12 , further comprising a second pressure sensitive adhesive that is pattern coated on the first major surface of the air and water barrier article.

14. The roll of claim 13 , wherein the first and second pressure sensitive adhesives are different pressure sensitive adhesives.

15. The roll of claim 1 , wherein all of the end groups of the polyoxyalkylene polymer are silyl terminated.

16. The roll of claim 1 , wherein the polyoxyalkylene polymer further comprises at least one silyl modified branched group.

17. The roll of claim 1 , wherein the polymeric material is a solid material or a foam material.

18. A self-adhering air and water barrier article derived from the roll of claim 1 , wherein the self-adhering air and water barrier article comprises the air and water barrier article having opposing first and second major surfaces, the pressure sensitive adhesive disposed on at least the first major surface of the air and water barrier article, and the liner having the first major surface in contact with the opposing second major surface of the air and water barrier article.

19. The self-adhering air and water barrier article of claim 18 disposed on a major surface of a building component.

20. The roll of claim 17 , wherein the foam material comprises closed cell foam.
