Abstract
A roll comprising an air and water barrier article is provided. The barrier article has opposed first and second major surfaces. A pressure sensitive adhesive is disposed on at least the first major surface and a release agent is disposed on the opposing second major surface. The release agent covers less than 100% of the second major surface and the pressure sensitive adhesive contacts predominately, if not exclusively, the release agent when wound in the roll.
Claims20
A roll comprising a vapor permeable, air and water barrier article with no liner present, the article having opposing first and second major surfaces, a pressure sensitive adhesive disposed on the first major surface of the article, and a release agent disposed on the opposing second major surface of the article, the release agent covering less than 100% of the second major surface, each of the pressure sensitive adhesive and the release agent are in the form of repeating pattern shapes, the pattern shapes being separated from adjacent pattern shapes, wherein the release agent pattern shape is larger than the pressure sensitive adhesive pattern shape and wherein the pressure sensitive adhesive contacts only the release agent when wound in the roll.
A roll comprising a vapor permeable, air and water barrier article with no liner present, the article having opposing first and second major surfaces, a pressure sensitive adhesive is disposed on the first major surface of the article, the pressure sensitive adhesive covering less than 100% of the first major surface, and a silicone release agent is disposed on the opposing second major surface of the article, the silicone release agent covers less than 100% of the second major surface, each of the pressure sensitive adhesive and the silicone release agent are in the form of repeating pattern shapes, the pattern shapes being separated from adjacent pattern shapes, wherein the silicone release agent pattern shape is larger than the pressure sensitive adhesive pattern shape and wherein the pressure sensitive adhesive contacts the silicone release agent when wound in the roll.
A method of forming a roll of a vapor permeable, air and water barrier article with no liner present, the article having opposing first and second major surfaces, the method comprising applying a pressure sensitive adhesive in a pattern on the first major surface of the article and applying a silicone release agent in a pattern on the opposing second major surface of the article, the silicone release agent covering less than 100% of the second major surface to provide a coverage area of silicone release agent and the pressure sensitive adhesive covering less than the coverage area of the silicone release agent on the second major surface, each of the pressure sensitive adhesive and the silicone release agent are in the form of repeating complimentary pattern shapes, the pattern shapes being separated from adjacent pattern shapes, wherein the silicone release agent pattern shape is larger than the pressure sensitive adhesive pattern shape and wherein the pressure sensitive adhesive contacts the silicone release agent when wound in the roll.
