solution to create a zinc layer on aluminium so that this can be further electroplated.
Then the coating is done with the basic/alkaline copper electrolyte.
We offer a solution with reduced viscosity here, as this has many advantages.
The advantages are:
- the lower viscosity reduces the entrapment of the solution in porous casting moulds (blistering of the subsequent coating)
- less loss of chemicals (especially in unfavourable moulds)
- faster deposition - higher safety when depositing on aluminium alloys containing magnesium and silicon.
Marking of the mixture:
(contains sodium hydroxide)
