Chromium free passivation solution for KaiMeng brand copper

Summary: This product is a long-term patented product developed by our company and well-known domestic universities. In view of the shortcomings of salt fog resistance for copper passivation all over the world, we break through the traditional formula of the current market and boldly adopt new synthetic materials and new technology that have never been before. At present, copper passivation has reached the world's leading level. It has an incomparable effect of traditional passivation with chromic acid and benzene handle. After chemical polishing, electrolytic polishing and mechanical polishing, the active metal surface is changed into inert metal surface, which can effectively prevent the oxidation of copper surface and keep the polished natural color.

Suitable material: suitable for all copper and copper alloy materials.

The powerful advantages of Kai Meng brand copper passivation are:

1. patent formula, patented product and market traditional product are incomparable.

2. Operate the simplex room without complex equipment and use it at room temperature.

3. high efficiency: passivation takes a short time and high efficiency.

4. High resistance to oxygen gasification and salt spray test are superior to chromic acid passivation.

5. safety and environmental protection, no harmful substances, odourless, waterborne products.

Usage method:

1. Use the polished copper immediately after polishing (because the copper is oxidized very quickly in the natural environment, it can be oxidized and discolored in a few hours). Clean it after polishing and soak it in the liquid for 8 minutes.

2. Remove after time and rinse with water.

3. Drying packaging (recommended drying temperature should not exceed 60 degrees, the best natural temperature "wind" dry), too high temperature will make copper yellowing.
