Reliant Aluminum Products, Clariant’s U.S. distributor, has introduced the Anodal Acid Etch System, a moderately acidic etch used for the pretreatment of anodized aluminum. According to the company, the system can produce a high quality, low gloss finish on low quality aluminum with only a fraction of the aluminum typically consumed during the etch process. A reduction of up to 80% caustic soda consumption, as well as production waste solids, can be expected by implementing the system in a conventional architectural anodizing line.
