Abstract: The present invention provides a panel sheathing for making wall and roof structures in which the panels (e.g., wood boards, oriented strand boards, plywood, etc.) are pre-coated at a factory, before installation at the building/construction site, using a polymeric barrier coating having specific water permeability, self-sealing properties with respect to penetrated metal fasteners (e.g., nails) in accordance with ASTM D7349 (modified using 1.5-5.0 inches water depth in hydrostatic head testing over sample of coated panel in which a steel nail is driven to within 1/8 inches of being flush with the panel and conditioning the test specimen for 24 hours at 23° C prior to hydrostatic loading), as well as anti-blocking properties whereby the coated panels can be transported in stacked configuration without sticking or disintegration of the polymeric barrier coating. The coated panels do not require the use at the installation site of felt paper, house wrap, or additional applied barrier coating to provide excellent weather barrier properties. The present invention also provides methods for constructing the panel sheathing structure as well as for making the coated panels.

Abstract: A water vapor impermeable flooring underlayment membrane of the present invention comprises a non-woven layer have first and second major faces, a first coating on the first major face of the non-woven layer, and, on the second major face, a water-vapor impermeable polymer layer, and a pressure sensitive adhesive layer partially coated on the polymer layer, the pressure sensitive partial coated adhesive layer being covered by a release liner. The use of partial coating pressure sensitive adhesive layer allows for quicker and more convenient floor installation compared to prior art box grid taping processes.

Abstract: Disclosed is a waterproofing membrane that comprises a carrier sheet, a pressure sensitive adhesive layer on one surface of the carrier sheet, and a protective coating layer on the adhesive layer. The protective coating layer comprises polyvinyl acetate (PVAc). The protective coating layer protects the membrane against weather exposure, tolerates foot traffic and strongly adheres to concrete cast against it.

Abstract: Disclosed are waterproofing membranes comprising the following laminated layers: layer A comprising a waterproofing adhesive; layer B comprising a carrier sheet; layer C comprising a releasable bonding material; and layer D comprising a protective coating; wherein (i) the laminated layers are arranged in the sequential order A-B-C-D; or (ii) the laminated layers are arranged in the sequential order B-C-D-A; or (iii) the laminated layers are arranged in the sequential order C-D-A-B. The membrane does not include a removable release sheet that is typically used to prevent the adhesive from adhering to the carrier sheet or other portion of the membrane when the membrane is rolled up. Also disclosed is a method of making the aforementioned membrane. Preferably, layer C will comprise a water soluble polymer, an alkali soluble polymer, or a homopolymer or copolymer of polyvinyl acetate.
