Acid Potassium Chloride Zinc Electroplating Softener
Brightener The main brightener can produce remarkable brightening and leveling effect. If the content is too high, the coating in the low current density area will become thinner, and the bottom will be exposed after passivation, which will easily lead to increased brittleness of the coating and affect the passivation quality. The content is too low, the coating bright leveling effect is not good. The content in the bath is maintained at 0.8-2ml/L.
