Acid Potassium Chloride Zinc Electroplating Brightener
USE: 1. Metal surface treatment electro-galvanized 2. Galvanized standard parts, such as screw, nuts, and bolts 3. Metal accessories and metal fittings need to be galvanized 4. Electric galvanizing parts color has silver white, blue white, and color
Description
It is characterized by simple electrolyte composition, stable electrolyte, fine coating, bright, high current efficiency, wide operating temperature range (5 ~ 60℃), simple wastewater treatment. The chemical dissolution of the anode in the electrolytic cell leads to the increase of the concentration of main salt ions in the electrolyte.
Our main products are chemical additives, which used in manufacture zinc electroplating bath, for improve the brightness of galvanized layer on metal surface.
