| abstract |
The invention relates to a reflector ( 1 ) for electromagnetic radiation in the wavelength range of 100 nm to 1 mm, having high resistance against weather and corrosion effects, comprising a metal reflector body ( 2 ) having a reflecting surface ( 3 ), or a reflector body ( 2 ) on which a reflective layer ( 9 ) is deposited, and a transparent cover layer ( 4 ) made of polysiloxane formed in a sol-gel process. In order to maintain the known advantages of sol-gel protective coatings and achieve a technologically more advantageous production method, according to the invention, the cover layer ( 4 ) is made of a cross-linked polycondensate product of at least one silicic acid ester and at least one cyclic siloxane oligomer comprising, alkyl, vinyl, and/or aryl groups. |
