Abstract:
1. A pliable reinforcement carrier membrane for use in a coated membrane composite, comprising: a pliable non-woven fibrous mat; the fibrous mat comprising entangled polymeric fibers and a hydrophobic binder that bonds the polymeric fibers together; the fibrous mat having a length, a width, and a thickness; the fibrous mat having a first major surface and a second major surface that are each defined by the length and the width of the fibrous mat; the first major surface of the fibrous mat having portions of a portion of the polymeric fibers of the non-woven fibrous mat protruding therefrom in extent and in sufficient amounts to give the first major surface of the non-woven fibrous mat a fuzzy characteristic to facilitate adhesion of a coating material to the first major surface of the fibrous mat; and the second major surface of the fibrous mat being a generally smooth, non-fuzzy surface; and wherein the hydrophobic binder is present on the second major surface of the fibrous mat; and the hydrophobic binder on the second major surface of the fibrous mat retains an innate tackiness and is present in an amount sufficient to increase surface friction of the second major surface of the fibrous mat.
