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/m2. Embodiments of the present disclosure include an acoustic damping article including a release liner; and an acoustic damping composition disposed on the release liner. The acoustic damping composition partially coats the release liner, and the acoustic damping composition has a Patterned Interlayer Stiffness of at least about 1 GN/m3.

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: 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: A light weight electrochromic dimmable mirror stack (300, 600) is presented that is composed only of solid-state layers (315, 615) with a total thickness of less than 50 micron and a reflector (310, 610). Normally such a kind of layered device suffers from iridescence due to interference of light waves reflecting at the interfaces between the layers of the electrochromic device. The solution provided by the invention is to pattern at least one of the layers (315, 615) in the device such that the interference effects are smeared out and a more neutral color is obtained. Various possible configurations are described and also the method to produce such a device.

Abstract: The subject of the invention is a water-impermeable flexible polyurethane foam obtained by reacting a polyol component, which comprises at least one hydrophobic polyol, with a polyisocyanate component in the presence of a foaming agent, characterized in that it has a compression force of less than or equal to 12 kPa for 50% compression. Advantageously it has a density not exceeding 150 kg/m3, preferably not exceeding 60 kg/m3. The foam may be obtained by a cast-foam manufacturing process or by molding. It can be used as a water-impermeable seal.

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: A 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.
