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.

Roll including air and water barrier article and method of using the same

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.

Air and water barrier articles

There is provided an article that includes a polymeric layer disposed on and covering a first major surface of an porous layer, an adhesive layer disposed on a second major surface of the elastic layer opposite the polymeric layer; and a liner disposed on a major surface of the polymeric layer opposite the first major surface of the elastic layer. The polymeric layer and the porous layer together form an air and water barrier that is water vapor permeable. The liner is water vapor impermeable. In a preferred embodiment the polymeric layer comprises a polyoxyalkylene polymer having at least one end group derived from an alkoxy silane. A method of applying the article to a surface of a building component is also provided.

Air and water barrier article with porous layer and liner

There is provided a self-sealing article comprising a polymeric layer disposed on and covering a first major surface of an elastic porous layer, wherein the article passes Modified Test 1 of ASTM D-1970/D-1970M-13 or Modified Test 2 of ASTM D-1970/D-1970M-13, or Modified Test 3 of ASTM D-1970/D-1970M-13, and further wherein the self-sealing article is water vapor permeable and an air and water barrier. There is also provided a linered version of the self-sealing article in which a liner is disposed on a major surface of the polymeric layer opposite the first major surface of the elastic porous layer.

Self-sealing articles including elastic porous layer

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.

Easy to apply air and water barrier articles

A flame resistant RFID tag comprises: a first flame resistant polymer film having a major surface; an RFID device secured to the major surface of the first flame resistant polymer film, the RFID device having proximal and distal surfaces and comprising an antenna electrically connected to an integrated circuit; and a first flame resistant pressure sensitive adhesive layer covering the distal surface of the RFID device. Methods of making the flame resistant RFID tags are also disclosed.

Flame resistant RFID tag and method of making the same

The invention provides protective articles comprising a backing that comprises a fluorinated polymer and a curable adhesive on at least one layer of the backing. The protective articles of the invention may be used to provide substrates or articles of the invention having a fluorinated surface. The invention also provides methods of preparing such articles, methods of repairing appliqu&#xe9;s, and methods of edge sealing appliqu&#xe9;s.

Protective articles

An article for reducing the drag caused by a fluid flowing over a surface comprises a backing layer having an outer, exposed patterned surface that reduces drag, and an adhesive bonding layer for bonding the backing layer to the surface of a substrate, the article being free of a reinforcing layer.

Drag reduction article and method of use

A multi-layer article comprising a substrate and a dehydrofluorinated fluoropolymer, wherein the dehydrofluorinated polymer contains substantially no grafted adhesion-promoting groups, and the dehydrofluorinated fluoropolymer contains sufficient carbon-carbon unsaturation to increase the adhesion between the dehydrofluorinated fluoropolymer and the substrate.

Method of improving adhesion between a fluoropolymer and a substrate

An article for reducing the drag caused by a fluid flowing over a surface comprises an outer layer having an exposed patterned surface that reduces drag, an inner reinforcing layer, and an intermediate layer for bonding the outer layer to the reinforcing layer.
