Anodic oxidation coating remover composition and method of removing anodic oxidation coatings

摘要

Anodic oxidation coatings are selectively removed from anodic oxidation-treated aluminum or aluminum alloy members by immersion in a solution composition. By using a remover composition characterized by containing phosphoric acid and a molybdate salt, it is possible to selectively remove the anodic oxidation coatings from the aluminum or aluminum alloy members without substantially dissolving the basis metal aluminum or aluminum alloy.
