When anodising aluminium, the natural oxidation of the surface is specifically influenced to create a robust protective layer. This protective layer consists exclusively of oxygen and aluminum and preserves the authentic character of the base material.
Colinal’s oxide layer impresses with its lightfast inherent coloration, which is available in six color gradations.
