          Product introduction

          At present, chromate passivation process with six or three valence is used for zinc plating. The government has strictly controlled the use of hexavalent chromate because of its high toxicity and carcinogenic potential. Trivalent chromium passivation also has many cracks, no automatic repair function, poor corrosion resistance and other problems.
          After several years of development, the company has completed the development of the world's leading level of chrome-free passivating agent, the product has passed SGS environmental protection certification, after a large number of customers use, proved that the product not only less, good luster, stable tank liquid, and its corrosion resistance can be fully comparable with the chrome-containing passivating liquid phase.
