Anodising Colours The anodising process produces a film which is porous. These pores make the anodic film strongly absorbent and, therefore, ideally suited to dyeing We operate a wide variety of dyes and are able to produce many different coloured finishes ranging from pale golds to deep blacks. We then use either hot or cold sealing to retain the colour and provide corrosion resistance to the product. Our standard colours are: Yellow Gold, Orange Gold, Green, Turquoise, Blue, Red (x2), Olive Brown, Violet and Black. We are happy to look at other colours if volumes justify it.
