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 ? 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.

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 is a waterproofing membrane that comprises a carrier sheet (layer A); a waterproofing adhesive (layer B); a protective coating (layer C), wherein the protective coating is substantially free of surfactant and comprises an acrylic or methacrylic polymer or copolymer, an inorganic filler and a white pigment; and a releasable material (layer D), wherein the releasable material comprises amorphous nanoscale silica and a polymeric binder. The waterproofing membrane does not require a release liner, binds strongly to concrete cast against it (even after UV exposure), tolerates foot traffic, and withstands immersion in water over an extended period.

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 a highly reflective protective coating layer operative to bond to concrete cast against it, particularly one that is produced from an aqueous coating comprising an acrylic emulsion, a filler, and a white pigment. The pigment volume concentration of the filler plus white pigment is greater than or equal to 40% by volume. The protective coating layer protects the membrane against weather exposure, tolerates foot traffic and strongly adheres to concrete cast against it. The protective coating comprises an acrylic polymer with a unique multi-domain morphology (i.e., at least two distinct polymer domains).

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.
