Mr. Ma from Nantong, Jiangsu Province, is the owner of an electroplating factory engaged in the production of zinc plating for various hardware fittings.Because several customers require that the workpiece should have a deep color passivation appearance that is resistant to salt spray, but the color zinc passivation agent that Mr. Ma has been using can't make the dark color, and the darker color will turn green, the color is very ugly, and the salt spray resistance effect of the workpiece is also poor.So Mr. Ma wants to find a trivalent chromium color zinc passivator with deep color and salt fog resistance.
One day, Mr. Ma saw Bigolly's trivalent chromium color zinc passivator BZ-207 in an online search, and asked whether the passivation agent could make the dark color he wanted.After understanding the production situation of Mr. Ma in detail, the Bigolly engineer provided Mr. Ma with several deep color workpiece renderings for comparison.After comparing the effect of the workpiece, Mr. Ma determined that it was the dark color he wanted.So Mr. Ma bought a few samples first.
Because this color zinc passivator BZ-207 is the technical support of European and American engineers, and is prepared with imported raw materials, the appearance color of the workpiece can be adjusted from yellow to purplish red to dark yellow, with good operability.Under the guidance of the engineer, Mr. Ma's work piece also easily obtained dark color, and the thickness was 5~8 μm workpieces can only pass the 72-hour neutral salt spray test before. Now they can pass the 120-hour salt spray test, and some have passed the 150-hour salt spray test. The salt spray resistance of workpieces has been greatly improved, and has also been recognized by many customers.So Mr. Ma signed a long-term cooperative purchase and sales contract with Bigolly.
Therefore, the color zinc workpiece cannot be passivated in deep color, and the salt fog resistance effect is poor. It is recommended to use this trivalent chromium color zinc passivator BZ-207 with deep color and salt fog resistance.If you are interested in this trivalent chromium color zinc passivator, you may contact Bigolly customer service for free samples and detailed technical information!
