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: The present disclosure provides an adhesive composition including a silicone-based adhesive and cellulose nanocrystals dispersed in the silicone-based adhesive. The present disclosure also provides an article including a substrate and a layer of the adhesive composition adhered to the substrate. Further, the present disclosure provides a method of making an adhesive composition. The method comprises mixing cellulose nanocrystals in a silicone-based adhesive to disperse the cellulose nanocrystals. The present disclosure additionally provides a method of making an article including disposing a layer of the adhesive composition on a substrate. The presence of the cellulose nanocrystals advantageously increases the water uptake capacity of the silicone-based adhesive while maintaining acceptable adhesive performance.
