Abstract
A weather and corrosion-resistant reflector with high overall reflection in the visible and infrared wavelength ranges. The reflector contains a reflector body with a reflection surface of an aluminum or aluminum alloy or a reflector body with a reflection coating of an aluminum or aluminum alloy. The reflector also contains an outer, final transparent protective layer of a sol-gel coating which is thicker than 1 .mu.m. The transparent sol-gel coating is a polymer of cross-linked inorganic siloxanes with alcohol groups that are bonded to the silicon with a carbon bond. The sol-gel coating is produced in a sol-gel process and, after having been applied to the reflector body, is dried and hardened using heat. The protective layer has excellent resistance to weather, corrosion and abrasion.
