    摘要: A process for making an aluminum alloy lighting sheet product having a reflective surface protected by a UV-stable polymer coating. An aluminum alloy sheet is chemically brightened in an aqueous acidic solution, conversion coated, and then coated with a UV-stable polymer. Alternatively, an aluminum alloy sheet is chemically etched in an aqueous alkaline solution, conversion coated, and then coated with a UV-stable polymer. Preferably, the UV-stable polymer contains about 0.5-10 wt. % amorphous silica particles. In another embodiment, an aluminum alloy sheet surface is cleaned, chemically conversion coated and then coated with a coating composition containing a UV-stable polymer and 0.5-10 wt. % of about 0.5-5 microns.

    摘要: A method of forming a highly-deflective surface on aluminum alloys. The, the composition comprising: cleaning a body formed from an aluminum alloy; electrobrightening the body; and desmutting the surface of the freshly-brightened body without etching. The bath comprises: 15-95 vol. % nitric acid and 1-85 vol. % acetic acid; 1-40 vol. % total water; and a source of fluoride ion supplying at least 35 grams per liter of fluoride. Ammonium bifluoride is the preferred source of fluoride.
