Acid Potassium Chloride Zinc Electroplating Softener
Solubilizing main brightener, auxiliary brightening effect, increase the coating thickness in low area, improve the depth capacity of the bath, reduce the surface tension of the bath, on the cathode surface wetting effect. The content in the bath is 25ml/L - 30ml/L The coating brittleness increases and passivation quality is affected by high content. The content is too low, the bright effect is not good, the coating is easy to flower, stay in the air and change color quickly.
