is applied as an addition to caustic soda for satin and matt finishes on aluminum parts by the immersion method before anodizing. With an aluminum content of 100-150 g/l this treatment imparts a uniform, matt, decorative appearance to the aluminum parts. Minor surface imperfections are usually completely or almost completely covered
prevents the formation and deposition of aluminate on the walls of the vessels and heating coils
