Abstract
Self-adhering articles comprising (i) a weather resistive barrier comprising a first nonwoven fabric attached to a first vapor-permeable and liquid impermeable (VPLI) film, (ii) an adhesive layer comprising an adhesive composition, in which the adhesive layer is located adjacent the first nonwoven fabric, and wherein the first nonwoven fabric is located between the first VPLI film and the adhesive layer; and (iii) a release liner located adjacent the adhesive layer, wherein the adhesive layer is located between the first nonwoven fabric and the release liner are provided.
Claims15
A self-adhering article, comprising:
- (i) a weather resistive barrier comprising a first nonwoven fabric attached to a first surface of a first vapor-permeable and liquid impermeable (VPLI) film, a second surface of the VPLI film comprising a first outer surface of the self-adhering article;
- (ii) an adhesive layer comprising an adhesive composition, the adhesive layer being located adjacent the first nonwoven fabric, wherein the first nonwoven fabric is located between the first VPLI film and the adhesive layer, wherein the adhesive layer comprises a discontinuous layer of the adhesive composition, the discontinuous layer of the adhesive composition including a plurality of discrete zones of the adhesive composition surrounded by a continuous zone devoid of the adhesive composition;
- (iii) a first surface of a release liner located adjacent the adhesive layer, wherein the adhesive layer is located between the first nonwoven fabric and the release liner, a second surface of the release liner comprising a second outer surface of the self-adhering article positioned opposite the first outer surface,
- wherein the first VPLI film comprises at least one propylene-containing copolymer, at least one polyethylene, at least one ethylene-containing copolymer, or any combinations thereof, and has moisture vapor transmission rate (MVTR) from at least about 10 US Perms to about 60 US Perms.

A self-adhering article, comprising:
- (i) a weather resistive barrier comprising a first nonwoven fabric attached to a first vapor-permeable and liquid impermeable (VPLI) film;
- (ii) an adhesive layer comprising an adhesive composition, the adhesive layer being located adjacent the first nonwoven fabric, wherein the first nonwoven fabric is located between the first VPLI film and the adhesive layer, wherein the adhesive layer comprises a discontinuous layer of the adhesive composition, wherein the discontinuous layer of the adhesive composition includes a plurality of discrete zones of the adhesive composition surrounded by a continuous zone devoid of the adhesive composition;
- (iii) a release liner located adjacent the adhesive layer, wherein the adhesive layer is located between the first nonwoven fabric and the release liner, wherein the first nonwoven fabric has a first end and a second end along a cross-direction, and wherein the plurality of discrete zones of the adhesive composition include a first discrete zone of the adhesive composition at or proximate to the first end, a second discrete zone of the adhesive composition at or proximate to the second end, and a plurality of intermediate discrete zones of the adhesive composition located between the first discrete zone of the adhesive composition and the second discrete zone of the adhesive composition;
- wherein the first discrete zone of the adhesive composition defines a first coating area, the second first discrete zone of the adhesive composition defines a second coating area, and the plurality of intermediate discrete zones of the adhesive composition have an average intermediate coating area per intermediate discrete zone, and wherein the first coating area and/or the second coating area is larger than the average intermediate coating area.
