Abstract:
The invention relates to a flexible watertight polyurethane foam obtained by reacting a polyol component comprising at least one hydrophobic polyol and a polyisocyanate component in the presence of a foaming agent. The invention is characterized in that it has a compression strength of less than or equal to 12kPa for 50 % compression. The density of the inventive foam is advantageously less than or equal to 150kg/m 2 , preferably 60kg/m 2 . The foam can be obtained by method for the production of couched foam or by moulding. The inventive foam can be used as a watertight joint.

Abstract:
The disclosure is directed to a framed device. The framed device includes a substrate, a frame, and a seal. The substrate has a first length, a first width, and a peripheral edge. The frame has a second length, a second width, and a groove that runs along the second length and the second width of the frame. The groove is substantially engaged with the peripheral edge of the substrate. The seal is disposed within the groove of the frame, wherein the seal runs contiguously from the substrate to the frame and the seal includes a foamed polymer.

Abstract:
Novel coating formulations and coating processes which have lower costs than TEDLA or KYNAR laminated backsheets, less curl than polyolefin laminated backsheets, excellent adhesion to encapsulant EVA, and better mar resistance on the surface facing the environment. In a preferred embodiment, the backsheet is formed by applying a distinct coating layer to each side of a film substrate. One coating layer is preferably a weather-resistant layer coated on the side of the substrate that will be exposed to the environment, while the other coating layer is a functional layer which provides excellent adhesion both to the substrate and to the EVA encapsulant layer.
Abstract:
An acoustic damping article includes a substrate, wherein the substrate has a surface area S. The acoustic composition further includes a polymer resin. The polymer resin coats partially the surface area with a set of areas. The ratio of the coated areas over the surface area S is less than 1 and the polymer resin coverage is not greater than about 500 g/m 2.

Abstract:
A method of forming a seal includes preparing a froth from a one component polyurethane precursor, applying the froth to a surface of an article, and simultaneously applying water with the froth, the froth curing to form a gasket having a density not greater than 350 kg/m3 bonded to the article.
Abstract:
A stud for a partition or wall has at least two frame members coupled together by a compliant member formed from a material that increases resilience between the frame members. The coupled frame members form a stud for the partition. The partition has a first stud with rigid first frame members coupled together by the compliant material. A second stud is joined to the first stud to form a frame. The second stud rigid second frame members are coupled together by the compliant material. Boards are joined to the frame on opposite sides thereof to form the partition.
Abstract:
The disclosure is directed to a framed device. The framed device includes a substrate, a frame, and a seal. The substrate has a first length, a first width, and a peripheral edge. The frame has a single, contiguous lengthwise piece having a first end and a second end, wherein the lengthwise piece is configured to form three corners by bending and is substantially equal to the length of the substrate. The frame further includes an attachment means connecting the first end and second end of the frame when in the bent position and a groove that runs along a length and a width of the frame, wherein the groove is substantially engaged with the peripheral edge of the substrate. The seal is disposed within the groove of the frame, wherein the seal runs contiguously from the substrate to the frame and the seal includes a foamed polymer.
