Positioning

Utilizes environmentally friendly nano passivation technology to directionally form a colorless transparent protective film on the copper surface, effectively isolating corrosive media such as oxygen, moisture, and perspiration.

Features

• Long-lasting oxidation resistance: After this passivation treatment, the anti-tarnish period of copper materials can be extended several times to over ten times, while maintaining good conductivity, thermal conductivity, and solderability of the substrate. The film does not affect welding or subsequent assembly — a long-term solution for preventing copper oxidation blackening and ensuring lasting appearance and functional stability.
