An adhesive tape and methods of use in cold or hot environments, such as in the construction industry, wherein the adhesive tape includes a pressure sensitive adhesive layer (preferably, an acrylic pressure sensitive adhesive layer) disposed on a backing (preferably, a multilayer backing).

Adhesive tapes and methods of use in construction

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.
