anodisation |
|
A two-step colour application method. The transparent anodised layer
produced during anodisation corresponds to the natural colour of aluminium
(EV 1).
Subsequent to this colourless oxidation, the layer can be electrolytically
coloured in a second step using a metal salt solution. The metal oxides
deposited in the open pores of the anodised coating produce colour shades
which are stable to light and whose brightness can be assessed from light
beige to bronze or even black (C11 – C14). The colour effect is
not created on the surface of the material, but at the bottom of the
pores of the anodised layer and so fully protected from environmental
influences.
