Sodium saccharin in electroplating

Nickel electroplating is a very important process of electroplating, especially bright nickel electroplating, which is needed for metal plating and plastic plating. More than 80% of plating factories have the nickel plating process. So, Today we will talk about the effect of sodium saccharin’s content to bright nickel electroplating.

Sodium saccharin as the brightener in the nickel plating liquid, which widely used as softener or stress reducer. Moreover, The content of sodium saccharin affects nickel plating quality. Lower content will cause the nickel layer brittleness and usually come with mist appearance. We can test it with Hull Cell by adding few more sodium saccharin, see if it can reduce the mist appearance. However, higher content will cause mist appearance while chromium plating process.

The solution is to add more sodium saccharin in electroplating if you put less. But how to reduce it if you put more?

According to our experience, hydrogen peroxide or potassium permanganate is not the most effective way to reduce sodium saccharin. The best way is using activated carbon. 1g activated carbon powder can reduce about 0.22g sodium saccharin for 1g/L consistency of plating liquid.
