Product Technical Data Sheet (TDS)
Product Name: Copper Passivation Agent  Model: TL-003
Product Introduction
Chromium-free copper passivator for environmental protection, extends the oxidation time of copper, effectively preserves the copper from discoloration for a period, and enhances its corrosion resistance.
Product Advantages
After treatment with copper material passivator, there will be no effect on the appearance or surface hardness of the workpiece.
2. After treatment with copper material passivator, it effectively prevents the risk of copper oxidation, with a uniform passivation film that does not affect the natural luster of the copper.
3. After being treated with copper material passivator, copper materials are less prone to pitting, black spots, and green rust, effectively extending their storage time.
4. Short passivation treatment time, fast speed, and the electrolyte can be reused multiple times.
5. The formed passivation film does not affect subsequent processing operations, and can be directly used for soldering and welding.
