摘要:
The invention relates to opaquely coloured, infrared-reflecting mouldings which are able to serve as an IR barrier layer and can be used, for example, in the construction trade or in automotive engineering as, for example, a vehicle roof module with thermal protection properties.
摘要:
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.
摘要:
A transparent plastic foil with improved weathering resistance and increased intrinsic stability is provided. The foil contains a) poly(meth)acrylate and polyvinylidene fluoride in a ratio of from 1:0.01 to 1:0.5 (w/w); and b) a mixture containing a UV stabilizer and a UV absorber. Use of the foil as a protective coating is also included.
摘要:
The invention describes a transparent foil composed of plastic with improved weathering resistance and increased intrinsic stability where the foil encompassesa) poly(meth)acrylate and polyvinylidene fluoride in a ratio of from 1:0.01 to 1:1 (w/w); andb) 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.
摘要:
The present invention relates to a laminate comprising at least one thermoplastic substrate and at least one colour layer, wherein the thermoplastic substrate comprises polyamide, to which at least one colour layer comprising polyurethane crosslinking has been applied.
摘要:
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.
摘要:
The present invention relates to a process for producing transparent polymeric films or plastics moldings of particularly high chemical resistance, having more particularly a very good resistance towards oil-in-water and water-in-oil emulsions, and of high optical quality.
