摘要
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.
