In the process of trivalent chromium black zinc passivation, often because of the poor impurity resistance of the working solution, the passivation film of the workpiece is not black enough or the corrosion resistance of the coating is poor, resulting in poor quality of the coating of the workpiece and low production efficiency.
Today we will introduce Bigely black zinc passivator to you and show you the reasons why you need to choose it.
1, it is formulated with imported raw materials, high purity with few impurities, stable tank liquid, low failure rate; high concentration of more than 20% higher than the counterparts, the dosage is provincial, more durable, lower production costs.
2, it is completely free of hexavalent chromium, the product is in line with the EU RoHS environmental requirements, just a simple impregnation, you can get a uniform and dense bright black passivation film.
3, the workpiece corrosion resistance is good, neutral salt spray test is greater than 72 hours, with sealer used together with better results.
