Abstract: The tape incudes a water vapor-permeable air and water barrier article and a pressure sensitive adhesive layer. The air and water barrier article includes a fibrous layer having first and second major surfaces and a polymeric layer on a first major surface of the fibrous layer that penetrates into the fibrous layer but leaves at least some fibers exposed on the second major surface. The pressure sensitive adhesive layer is on the polymeric layer of the air and water barrier article. The tape can retain greater than 50 percent by weight of mortar applied according to the Vertical Mortar Receptivity Evaluation. The article includes a substrate, the tape, and a composite layer comprising at least one of gypsum, lime, or cement. The composite layer is at least one of dried or cured on the second major surface of the fibrous layer. Methods of making the article are also described.

Abstract: A transparent conductor is provided, including a visible light transparent substrate and metal traces disposed on the substrate, and a layer of a second metal deposited on at least a portion of the metal traces. The transparent conductor further includes a layer of a second metal, which conforms to the surface structure of the metal traces on which it is deposited. Optionally, the transparent conductor also includes a coating layer disposed on a portion of the metal traces and the substrate surface. The coating layer includes a polymer prepared from a polymerizable composition containing at least one ionic liquid monomer. A method of forming a transparent conductor is also provided, including obtaining a visible light transparent substrate having metal traces disposed on the substrate and applying a coating composition on a portion of the metal traces and substrate. The coating composition contains at least one noble metal salt and at least one polymerizable ionic liquid monomer.

Abstract: A film is described comprising a first film layer having a Tg ranging from 30° C. to 60° C. The first film layer comprises a (meth)acrylic polymer and polyvinyl acetal polymer composition. The film further comprises a second layer proximate the first film layer. The second layer is different than the first film layer. The second may be a cured (meth)acrylic polymer film or coating; a backing such as thermoplastic polymer, woven or nonwoven fabrics, metal foils, paper, foams; or a coverfilm such as a fluoropolymer.
