FULLY-ADHERED ROOFING SYSTEMS UTILIZING A PRIMER HAVING A SILICON-TERMINATED POLYMER
A method of installing a roof system includes providing a first membrane composite; adhesively securing the first membrane composite to a roof surface through a UV-cured pressure-sensitive adhesive layer; providing a second membrane composite; adhesively securing the second membrane composite to the roof surface through a UV-cured pressure-sensitive adhesive layer, where the second membrane composite is positioned adjacent to and partially overlapping a lap area of the first membrane composite; and adhesively securing the second membrane composite to a first planar surface of the first membrane composite along a primer layer through the UV-cured pressure-sensitive adhesive layer disposed on the second membrane composite.
Dielectric composite with reinforced elastomer and integrate electrode
The present disclosure is directed to dielectric elastomeric composites that include a retainable processing membrane, an elastomer material, and an electrically conductive material. The elastomer layer may be partially imbibed into the retainable processing membrane. The retainable processing membrane may be porous. The retainable processing membrane is compacted in the transverse in direction, machine direction, or in both directions prior to the application of an elastomer material and an electrically conductive material. The compaction of the retainable processing membrane may form structured folds or folded fibrils in the membrane, giving the retainable processing membrane a low modulus and flexibility. In some embodiments, the dielectric composites are positioned in a stacked configuration. Alternatively, the dielectric elastomeric composites may have a wound configuration. The dielectric composites have a total thickness less than about 170 μm. The dielectric elastomeric composites may be used, for example, in dielectric elastomer actuators, sensors, and in energy harvesting.

Graphic sheet, method of producing graphic sheet, and building structure
A graphic sheet is provided that can be affixed with sufficient adhesive force onto wallpaper, a poster, or other substrate having comparatively low strength, and can be easily renewed without damaging the substrate, which is the underlying layer. A graphic sheet of an embodiment of the present disclosure includes: a base film layer having a first surface and a second surface situated on an opposite side of the first surface; and a tacky acrylic foam layer disposed on or above the second surface of the base film layer. The acrylic foam layer contains an acrylic polymer having 20 mass % or more of a unit derived from ethyl acrylate.
A SEALING DEVICE WITH INCREASED SURFACE ROUGHNESS
A sealing device includes a functional layer having a first major surface and a second major surface and a barrier layer directly or indirectly connected to the second major surface of the functional layer, wherein the functional layer has a surface roughness having a waviness factor W.sub.f. Also disclosed is a method for producing a sealing device and the use of a sealing device for waterproofing of a substrate.
Depth-Independent Blast-Resistant Thermally-Insulating Ballistically-Protective and Ergonomically-Improved Segmented Diver Suit
A segmented diving suit includes a base layer and a plurality of composite plates arranged on the base layer in a configuration designed to avoid joints or other anatomical features that bend. The composite plates include a spheres or microspheres dispersed/embedded in a carrier polymer. The spheres or microspheres provide one or more of thermal protection, sonic/blast resistance, and ballistic protection.
