.Process characteristics: Renchang's corrosion-resistant aluminum alloy zinc immersion liquid is a zinc immersion agent that needs to be used in conjunction with trace substances.
It can produce a dense and uniform thin zinc layer on the surface of aluminum alloy, providing good bonding force for subsequent processes such as direct copper plating, nickel plating, tin plating, chemical nickel plating, etc.
Especially suitable for electroplating aluminum alloy wheels.

3. Notes:
Supplement B is strongly alkaline Solution should be added in small amounts and multiple times with stirring to avoid local overheating of the solution during work.
The working fluid contains chemicals, so be careful when handling it to avoid mixing it with acid, which may cause danger.
Do not add a large amount of additives during production, but add small amounts multiple times to mix the working solution evenly and avoid roughening the working surface.
The working temperature should be less than 3℃. If the temperature is too high, the zinc crystal will be rough and the bonding force between the substrate and the subsequent electroplating layer will be reduced.
