Many customers prefer the color appearance of hexavalent chromium passivation, and the use of trivalent chromium color zinc passivator, the color appearance of the workpiece does not meet the requirements, or the corrosion resistance of the workpiece coating is poor and affects the performance of the workpiece. Today, we introduce a trivalent chromium color zinc passivator BZ-207 with hexavalent chromium passivation appearance and high corrosion resistance.
BZ-207 is a high corrosion resistance trivalent chromium color zinc passivator developed by Bigely Technology. The solution has passed SGS test, does not contain hexavalent chromium, and complies with ROHS regulations. Uniform and bright color zinc passivation film can be obtained at room temperature, and the color of the film can reach the yellow color similar to the passivation of hexavalent chromium color zinc.
The corrosion resistance of the coating is better than that of traditional trivalent chromium color passivation. General trivalent chromium color zinc passivation solution passivation workpiece, its neutral salt spray test time is 72-120 hours; For BZ-207 passivated workpieces, the neutral salt spray test time is more than 150 hours.
BZ-207 trivalent chromium colored zinc passivator has a wide range of operation processes, is used at room temperature, and is excellent, fast, easy to maintain and control. It has high impurity tolerance, long service cycle, saving production costs.
After using BZ-207 trivalent chromium color zinc water, Mr. Lin of Bigely customer has uniform color appearance of the product, good corrosion resistance after passivation of the workpiece, good stability of the passivation solution, easy maintenance and management, which can meet the appearance and performance needs of different customers.
If you need a trivalent chromium colored zinc passivator with such appearance and performance, please call us.
