Previously, Mr. Chen used a certain brand of acid zinc plating brightener, which resulted in a high amount of organic decomposition products in the plating solution. The coating on the workpiece was prone to adhering to these organic substances, and even after two washes, it could not be cleaned completely. After passivation, the coating on the workpiece was prone to discoloration. So Mr. Chen wants to replace it with an acidic zinc plating brightener with less organic impurities and less discoloration of the coating.
The hanging tin plating solution has more foam and is prone to turbidity. Try this matte tin plating additives
Neodymium iron boron workpieces are prone to rust and poor adhesion when plated with nickel. Try this electroless nickel plating agent quickly.
The nickel layer on the workpiece is prone to yellowing and discoloration before tin plating. Try this high temperature nickel additive
The dispersion ability of acidic tin plating solution is poor. Try this acid tin plating brightener quickly
Recommend a trivalent black zinc passivation solution with high salt fog resistance, which is worth purchasing!
