Systems and methods are described herein for manufacturing and using roofing membranes that are faster and easier to install than conventional adhesive-only membrane materials. In some embodiments, membrane materials are surface treated using a plasma flow, e.g., a blown-arc plasma flow, atmospheric plasma, corona plasma, or from portable plasma units, generated by passing a compressed plasma-generating gas through an electrical current to form the plasma-treated roofing membrane. The plasma treatments described herein may be applied as part of the manufacturing process, or in-situ at the site of roof installation. In some embodiments, membrane materials have surface chemistries, roughnesses and other surface characteristics that yield desired adhesion properties.

Sound absorbing or attenuating laminate flooring materials are provided, which are directed to be used in the production of floor covering, floor panels, furniture panels, cabinets, counter-tops and wall panels. As well, the methods for producing such products are provided. In particular, abrasion resistant panels, with a laminated structure, created by forming an assembly which consists of laminating a heat-activated resin impregnated paper wear layer, a decorative layer with printed graphics or a wood veneer decorative layer, a medium density (MDF) or high-density (HDF) natural fiber-based core and a resin impregnated paper balancing layer. To achieve sound absorbing and/or attenuating properties, any or all paper layers may be pre coated with an additional flexible elastomeric coating, film or material prior to assembly of the panel, or the natural fiber core panel may be coated with a flexible elastomeric coating, film or material prior to assembly with the papers. The flexible elastomeric coating, film or material acts to absorb, reduce, and/or ameliorate the sound transmissions inherent in laminated panels.

The present application provides compositions, methods of making the compositions, methods of using the compositions, and kits having instructions for using the compositions for providing a bond between synthetic polymers or between a synthetic polymer and another type of substrate.

A wear panel for mining and materials handling applications is provided. The wear panel includes a housing matrix (1) with a top surface (2), a bottom surface (3) opposite the top surface (2) and at least one cavity (4) with cavity walls (5). The cavity (4) extends through the top surface (2) and the bottom surface (3). The wear panel also includes at least one wear-resistant member (6) with a preformed shape. The at least one wear-resistant member (6) has a top surface (7) and a bottom surface (8) opposite the top surface (7). The wear-resistant members (6) are disposed in the cavity (4) and are locked into place by their preformed shape and the cavity walls (5).

Provided is a resin composition including 40 to 99% by mass of a fluorine-based resin (A), and 1 to 60% by mass of a matting agent (B), in which a swell ratio as measured under the conditions of a measurement temperature of 230 C., an ambient temperature of 23 C., and a shear rate of 96 (1/sec) is 0.90 to 2.00.

Building materials described herein include a structure having a substrate and a coating formed on the substrate. In one embodiment, the coating may include a mixture or rubber in urethane. For example, in one embodiment, mixture may include approximately 8% to approximately 12% by weight of urethane, approximately 2% to approximately 5% by weight of water, and approximately 81% to approximately 90% by weight of rubber. In some embodiments, the mixture may include a colorant, a fire retardant, and/or an ultraviolet (UV) inhibitor.
