Asymmetric articles are described including a porous substrate with two opposing major surfaces and a porous structure extending between the surfaces, and a polymeric coating on one of the major surfaces and extending into the porous structure to a depth of the porous structure. Methods for making an asymmetric composite article are also provided, including providing a porous substrate, treating the porous substrate with a plasma treatment or a corona treatment from one major surface to a depth of the porous structure between the two major surfaces. The method further includes applying a coating solution to the treated porous substrate and drying the coating solution to form a composite asymmetric composite article having a polymeric coating on one major surface and extending into the porous structure to the depth of the treated porous structure.

Asymmetric articles with a porous substrate and a polymeric coating extending into the substrate and methods of making the same

Blended, release materials containing crosslinked silicones, crosslinked fluorosilicones, and nonfunctional fluorosilicones are described. Articles including release liners and adhesive articles are also described, as are methods of making such blended release materials and articles incorporating them.
