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.

Tape, article including tape and composite layer, and related methods

The current technology relates to filter media configurations where the filter media has a surface with a treatment that increases the roll off angle of the surface for a 50 μL water droplet when the surface is immersed in toluene. Some example filter media have a fluted configuration, and some example filter media have multiple layers. Filter media having multiple layers can be single facer media, for example, where one layer is planar and another layer is fluted.

Filter media configurations

A substrate for use in a filter media including, for example, in a hydrocarbon fluid-water separation filter; methods of identifying the substrate; methods of making the substrate; methods of using the substrate; and methods of improving the roll off angle of the substrate. In some embodiments, the substrate includes a hydrophilic group-containing polymer or a hydrophilic group-containing polymer coating.
