This Zincate Dip delivers a protective layer of zinc onto the surface of aluminium. Once this protective layer is in place the aluminium can then be electroplated.

Zincate dip produces a dense, continuous immersion layer of zinc on aluminium, which can be subsequently plated with other metals. The best method is to tank plate copper (Copper Strike Tank  Plating Solution) or directly with nickel (Nickel Tank Plating Solution).
We recommend, if copper plating, to plate for approximately 5 minutes with Copper Strike then transfer to our copper electroforming solution to build up a thicker layer if required.
It is possible to brush plate small, non-complex zincated aluminium articles for functional purposes such as electrical contacts. We recommend thickening the brush plating solution first with Thickener before starting plating. We do not recommend the brush plating process is used for decorative items such as mobile phones.
Adhesion can be improved by stripping the zincated layer off in ActiClean then re-zincating. Please refer to Tech Specs for more information.

Notes:

  • The aluminium article should be dipped until a continuous grey film appears.
  • After  the zincate dip, quickly rinse and dry the article with a clean paper towel.
    Then plate with gelled Nickel Brush Plating Solution.
  • For maximum adhesion, heat treat at 250 – 300 centigrade for an hour after zincating
    (and drying with a clean paper towel) but before nickel plating.
  • If left in the solution too long, the adhesion of the zinc film is reduced, leading to
    blistering and in extreme cases, lifting of the plating.
  • To strip the zincated layer, dip in ActiClean  for 10 minutes. Please note that once
    the ActiClean has been used for stripping, it cannot be used for any other process.
