Description

Zinc chloride as the main salt, is also a conductive salt, it in the plating solution all ionized into chloride ions and zinc ions, ionized zinc ions will be directly on the plating part of the cathode reduction into a coating, can increase the conductivity of the plating solution, its concentration allowed to change in a wide range. It is easy to absorb moisture, easy to dissolve, exothermic phenomenon.
