Description

Additives play an important role in plating solution. In general, additives are added according to KA.h consumption. If the proportion is out of proportion, add it according to the bath volume after adjusting by hull bath experiment.

Without additive plating solution, the coating is gray and rough, and the range of cathode current density is very small.

After adding appropriate amount of additives, the coating can be fine and bright, the current density is expanded, the dispersion ability and covering ability are improved, too high additives will cause brittleness of the coating, passivation film fall off and color change.

The general total amount should be controlled within the range of 25-30ml/L.
