DL-22 Neutral Pre-Nickel Plating Process
1. It can be used as pre-coating of aluminum alloy after zinc deposition.
2. Ensure that the zinc layer is not damaged.
3. The crystallization of the coating is meticulous and soft, and the bonding force with other coatings is good.
4. It is also suitable for nickel plating process of zinc alloy substrate instead of cyanide copper plating process.
