Abstract

The roll includes an air and water barrier article, a pressure sensitive adhesive disposed on the first major surface of the barrier article, first and second coating compositions disposed on the opposing second major surface of the barrier article, and a liner having a first major surface in contact with the first coating composition and the second coating composition. The first coating composition has a first peel adhesion to the first major surface of the liner that is lower than a second peel adhesion of the second coating composition to the first major surface of the liner. The pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll, and a peel adhesion between the second major surface of the liner and the pressure sensitive adhesive is less than or equal to the second peel adhesion. There are also provided methods of applying barrier articles, films made using these 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 and a length;
a pressure sensitive adhesive disposed on at least the first major surface of the air and water barrier article;
a first coating composition and a second coating composition disposed on the opposing second major surface of the air and water barrier article; and
a liner having a first major surface that is in contact with the first coating composition and the second coating composition, wherein the first coating composition has a first peel adhesion to the first major surface of the liner that is lower than a second peel adhesion of the second coating composition to the first major surface of the liner,

wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll, and wherein a peel adhesion between the second major surface of the liner and the pressure sensitive adhesive is less than or equal to the second peel adhesion.

2. The roll of claim 1 , wherein a sum of the first peel adhesion times the fraction of a peel front provided by the first coating composition and the second peel adhesion times the fraction of a peel front provided by the second coating composition is greater than or equal to the peel adhesion between the second major surface of the liner and the pressure sensitive adhesive.

3. The roll of claim 1 , wherein the first peel adhesion is less than or equal to 2 Newtons per decimeter.

4. The roll of claim 1 , wherein a ratio of the first peel adhesion to the second peel adhesion is in a range from 1:2 to 1:20.

5. The roll of claim 1 , wherein the first coating composition forms at least one continuous strip extending along the length of the roll.

6. The roll of claim 1 , wherein at least one of the first coating composition or the second coating composition is discontinuous.

7. The roll of claim 1 , wherein at least one of the first or second coating compositions comprises at least one of a polyamide, a polyurethane, a vinyl polymer, an acrylic polymer, or a nitrocellulose polymer.

8. The roll of claim 1 , wherein the liner comprises at least one of a polyester film, polyethylene film, polypropylene film, a polyolefin coated polymer film, polyolefin coated paper, an acrylic coated polymer film, and polymer coated kraft paper.

9. The roll of claim 1 , wherein at least one of the first major surface of the liner or the second major surface of the liner comprises a release coating.

10. The roll of claim 1 , wherein the air and water barrier article and the pressure sensitive adhesive together form a construction that is water vapor permeable.

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

12. The roll of claim 1 , wherein a width of the roll is at least 2.5 centimeters.

13. 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.

14. 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.

15. The roll of claim 14 , wherein the polymeric material comprises a polyoxyalkylene polymer having at least one end group derived from an alkoxy silane.

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

17. The roll of claim 1 , wherein the second coating composition occupies a greater area than the first coating composition.

18. The roll of claim 17 , wherein a ratio of an area of the second coating composition to an area of the first coating composition is at least 2:1.

19. A method of applying an air and water barrier article, the method comprising:
adhering at least a portion of the pressure sensitive adhesive on the roll of claim 1 to a surface of a building component, so that the air and water barrier article is affixed to the surface of the building component; and
unwinding at least a portion of the roll, wherein during the unwinding, the liner releases from the pressure sensitive adhesive and remains adhered to at least the second coating composition on the air and water barrier article.

20. The method of claim 19 , further comprising peeling the liner away from the first and second coating compositions on the air and water barrier article, wherein peeling is initiated at a location of the first coating composition.
