| 摘要 |
A composite sheet useful as a housewrap is provided having a textile substrate, with a cellular, polymer layer coated on at least one side of the substrate, wherein the cellular, polymer layer is created by applying a foamed, latex coating and heating the latex to create a semi-rigid, cellular membrane, and a water repellant finish applied to the outer surface of the textile substrate or the polymer layer. The properties of the composite sheet may be further modified by calendering, to reduce the overall thickness of the sheet by 50% or more. |
