Anodal® EC-2
- is applied as an addition to caustic soda for satin and matt finishes on aluminum parts by the immersion method before anodizing.

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
