20080293837 | Fluoropolymer Modified Acrylic Capstock - The invention relates to the use of an impact-modified acrylic blend with a low level of fluoropolymer to achieve impact resistance and solvent resistance in a capstock formulation. Preferably the acrylic blend contains a methyl methacrylate-based acrylic polymer and polyvinylidene fluoride. | 11-27-2008 |
20100000601 | PHOTOVOLTAIC MODULES HAVING A POLYVINYLIDENE FLUORIDE SURFACE - The invention relates to a photovoltaic module for capturing and using solar radiation having as a transparent glazing a thermoplastic structural component covered by a thin polyvinylidene fluoride layer The polyvinylidene fluoride layer is exposed to the environment and provides a chemical resistant and dirt shedding surface. The structure may contain a tie layer between the polyvinylidene fluoride layer and the structural thermoplastic to aid in adhesion. | 01-07-2010 |
20100175742 | PHOTOVOLTAIC MODULES HAVING A POLYVINYLIDENE FLUORIDE BACKSHEET - The invention relates to a photovoltaic module for capturing and using solar radiation having as a backsheet a composition containing polyvinylidene fluoride. The polyvinylidene fluoride backsheet layer is exposed to the environment and provides chemical resistance, low water vapor transmission, electrical insulation, and UV light protection. | 07-15-2010 |
20110081553 | MELT IN PLACE BINDERS FOR BINDING PARTICULATE FILLERS TO SUBSTRATES - The invention relates to the use of a melt-in-place acrylic binder that is applied to a substrate in the form of a powder, followed by a fusing together of the binder powder by heat or radiation. Particulate filler is present either on the substrate, mixed with the binder powder, or admixed into the binder powder prior to fusion. The fused binder helps adhere the particulate fillers to the substrate, and may or may not cover the particulate filler. | 04-07-2011 |
20110226313 | HIGH TEMPERATURE ACRYLIC SHEET - The invention relates to an acrylic sheet having a high Tg, and especially for the use of the high Tg acrylic sheet as a front sheet of a photovoltaic module. The high Tg acrylic polymer is a copolymer of polymethylmethacrylate and one or more higher Tg monomers. | 09-22-2011 |
20110250435 | NANO-STRUCTURE COATED SHEETS/FILMS FOR OPTICAL ELECTRONIC DISPLAYS AND PHOTOVOLTAIC MODULES - The invention relates to a thin, nano-structured coating that provides optical light efficiency enhancement. The dried coating contains nano-structures that provide a very low haze level of less than 2 percent, and a light transmission improvement of at least 1% over the non-coated substrate. For the nano-structured coating on an acrylic substrate the transmission is greater than 93 percent, and preferably greater than 94 percent. The coatings of the invention are especially useful for optical electronic displays and photovoltaic modules. | 10-13-2011 |
20120024353 | THERMOFORMABLE PHOTOVOLTAIC BACKSHEET - The invention relates to high Tg monolithic and multi-layer thermoformable film or sheet useful as a backsheet on a photovoltaic module (PV). A methacrylic-based material is preferred. The film or sheet is formed of a composition having a Tg greater than 110° C. The methacrylic composition may be a blend of a polymethyl methacrylate polymer and a miscible or semi-miscible high Tg polymer, or may be a copolymer containing primarily methyl methacrylate monomer units. The backsheet is optionally covered with a fluoropolymer or acrylic/fiuoropolymer covering on the outside (side facing the environment). The back-sheet can be clear, white, and/or pigmented. The film or sheet is especially useful in concentrating photovoltaic modules (CPV), and is also useful in thin film photovoltaic modules. | 02-02-2012 |
20150024146 | MELT IN PLACE BINDERS FOR BINDING PARTICULATE FILLERS TO SUBSTRATES - The invention relates to the use of a melt-in-place acrylic binder that is applied to a substrate in the form of a powder, followed by a fusing together of the binder powder by heat or radiation. Particulate filler is present either on the substrate, mixed with the binder powder, or admixed into the binder powder prior to fusion. The fused binder helps adhere the particulate fillers to the substrate, and may or may not cover the particulate filler. | 01-22-2015 |
