Aluminium pre-treatments are required to create a layer that is suitable for subsequent electroplating and ensures good adhesion. For this purpose, Schlötter offers proprietary aluminium pickles for roughening the surface or for creating specific optical features which can also be used for anodising. Cyanide based and cyanide free Zincate pickles produce a base layer that is suitable for subsequent chemical or electrolytic coating processes.
– all process sequences for electroless and electrochemical coatings of aluminium or aluminium alloys
– pre-treatments prior to anodizing
Cyanide Pickle for pre-treatment of aluminium to allow electroplating.
Pickle additive for long-running pickles with sodium hydroxide content
Produces a zinc layer on aluminium and its alloys which allows for direct plating.
Cyanidic pickle for pre-tratment of aluminium before electro- or electroless plating.
Acid aluminium pickle. Especially suitable for aluminium alloys.
