Abstract: Disclosed are methods, compositions, and composition packages for spray-coating a membrane for waterproofing a concrete tunnel applications. After primer coating is applied onto a surface in the tunnel, the coating composition is sprayed to form a membrane, and then concrete is cast or sprayed against the membrane so that it can bond to the membrane. Coating compositions comprise two or more acrylate monomers, as well as initiator, accelerator, and optional additive. Preferably, the coating composition is established by using a two-part package, one part having initiator, the other part having accelerator, and each part containing the monomers and optional additives so that the two parts can be shipped to the application site and mixed in a 1:1 ratio during spraying. The waterproofing coating composition provides excellent bonding with concrete.

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 ⅛ 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 pressure-sensitive adhesive (PSA) composition and method of use across a wide operable temperature window. The PSA composition includes a triblock copolymer rubber with relatively low diblock content, an aliphatic tackifier, an aromatic tackifier, and an oil-based plasticizer. The combination of components results in the PSA having a phase-separated morphology, where the PSA includes two domains that do not mix with each other. This morphology’ results in superior performance of the PSA across a wide range of temperatures, such that separate adhesives for low temperatures and high temperatures are no longer required.
