  • Patent number: 8206782
    Abstract: The present invention describes a process for the surface finishing of materials via application of specific polymethacrylate layers. The polymethacrylate layers are composed of blends of at least two (co)polymers of polymethacrylates, and specific “reactive monomers” are present here in a polymerized mixture which forms the polymethacrylate layer. At the application temperature established, these form a chemical and, where appropriate, also a physical bond to the substrate, and therefore have adhesion-promoting action.

  • Publication number: 20120107609
    Abstract: The invention relates to a film composite and the use thereof as a mirror film in solar reflectors in view of the sustainable guarantee of the required reflection of solar radiation (total solar reflection). In particular, the invention relates to the use of cover films on the basis of polymethyl methacrylate (PMMA) in the film composite, having an especially high UV stability, and a high weathering stability. The invention further relates to a UV and weather protection package for said solar mirror film, as utilized in solar reflectors, for improving the optical life span, weathering stability, and for avoiding delamination. The invention further relates to a surface finish with regard to scratch resistance, anti-soil and chemical stability of the solar mirror film.

  • Patent number: 8088847
    Abstract: The invention relates to a novel UV-protective and weather-resistant package for surface protecting films for polyvinyl chloride window profiles made of poly(meth)acrylate. Matrix plastics having great molecular weights are used in order to obtain great weather resistance of the surface protecting films.

  • Publication number: 20100189983
    Abstract: The invention describes a transparent foil composed of plastic with improved weathering resistance and increased intrinsic stability where the foil encompasses a) poly(meth)acrylate and polyvinylidene fluoride in a ratio of from 1:0.01 to 1:1 (w/w); and b) a mixture composed of UV stabilizers and of UV absorbers. PMMA matrix plastics with high molecular weights and with a certain selected coacrylate proportion are preferably used in order to achieve excellent weathering resistance, and also improved intrinsic stability of the surface-protection foils.

  • Patent number: 7754317
    Abstract: The present invention relates to a foil encompassing at least one PMMA layer coloured with a yellow anthraquinone dye, where the chromaticity coordinates (x;y) in the CIE 1931 Standard Colorimetric System of the PMMA layer are within the range of 0.4?x?0.54 and 0.44?y?0.54, where the concentration of the yellow dye of the PMMA layer is at least 3% by weight, based on the total weight of the PMMA layer.

  • Publication number: 20080193729
    Abstract: The invention relates to a film membrane which has excellent weathering resistance and high permeability to thermal insolation, and is an effective barrier to thermal radiation emitted from the ground and has high mechanical strength, and also to a process for the production of the film membrane. The properties are achieved via a composite of a base film of thermoplastic and an outer layer of poly(meth)acrylate. The adhesion is achieved via copolymers with polar character. One or more layers of the plastics moulding may also have been equipped with flame retardants.
