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: Acrylic pressure-sensitive adhesive (“PSA”) compositions crosslinked with a small-molecule crosslinker containing a single, thermally reversible moiety represented by the structure (I) (Formula I)). wherein each R1 is independently —H or —CH3, each X is independently C2-C6 alkyl, and each R2 is independently a C1-C6 alkyl group or an aromatic group. Under high temperature conditions the crosslinks may be broken, thus allowing for good coating and dispensing of the PSA. Upon cooling, the crosslinks reform to create a gelled PSA network without need of additional post-processing curing steps.
