Solar mirror film composite with particularly high weathering and UV resistance

The invention relates to a film composite and its use as a mirror film in solar reflectors under the context of sustainable possible ensure the required reflection of solar radiation (total solar reflection). In particular, the invention relates to the application of cover films based on polymethyl (meth) acrylate (PMMA) in the film composite, with a particularly high UV stability and a high weather resistance. Further, the invention relates to a UV and weather protection package for said solar reflective foil, such as are used in solar reflectors, to improve the optical durability, weather resistance and prevention of delamination. The invention further relates to a surface coating, on scratch resistance, and chemical resistance of the solar Antisoil mirror film.
