Patent ID: 7998530

Claim:
A method for the manufacture of a coated substrate, having a moisture vapor permeable air and water barrier, of greater than about 0.949 metric Perms, on at least one surface of the substrate, comprising the steps of: 1) providing at least one aqueous composition comprising; a) at least one water-based film forming polymer in a range from about 10-50%: b) at least one non-crystalline silica or silicate mineral in a range from about 8-38%: c) at least one mineral filler in a range from about 2-30%: d) at least one fungicide in a range from about 0.05-4%: e) at least one ultraviolet light absorbing component in a range from about 0.1-40%: f) at least one dispersant in a range from about 0.1-3%; and g) at least one surfactant in a range from about 0.1-2%; then. 2) providing at least one substrate; 3) applying said composition onto said substrate to form a wet-coated substrate; 4) drying the wet-coated substrate to form a dry coated substrate having a dried barrier-composition thereon.
