DL-22 Neutral Pre-Nickel Plating Process

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.

DL-23H Descaling Acid Etching Agent

DL-23H Descaling Acid Etching Agent

1. This process is specially used in descaling solution. 2. It can effectively remove the residue retained on the aluminum surface after weak corrosion, and can effectively prevent the over corrosion of the aluminum surface. 3. The brightness of the low current area is especially obvious, which can effectively reduce the polishing pressure.

DAL-2000 zinc precipitation agent

DAL-2000 zinc precipitation agent

1. It can replace the surface of aluminum alloy to produce a zinc layer containing copper, iron and nickel, and the zinc layer is fine and uniform. 2 for the subsequent chemical nickel, copper plating, tin plating, etc. to provide a good binding force. 3. If necessary, zinc can also be deposited twice.

DAL-2100 Cyanide-free zinc precipitation agent

DAL-2100 Cyanide-free zinc precipitation agent

1. The zinc coating is very fine, thin and uniform, and has good adhesion to aluminum. This process can not only deposit a uniform zinc coating on the wide and flat surface of aluminum alloy, but also be more suitable for plating aluminum alloy workpieces with blind holes, gaps, threads and grooves. 3. If necessary, secondary zinc precipitation can also be done. 4. Will not damage the surface of the plated parts. 5. This process does not contain cyanide, environmental protection and safety.

DAL-2200 Cyanide-free zinc precipitation agent

1. The zinc coating is very fine, thin and uniform, and has good adhesion to aluminum. This process can not only deposit a uniform zinc coating on the wide and flat surface of aluminum alloy, but also be more suitable for plating aluminum alloy workpieces with blind holes, gaps, threads and grooves. 3. Suitable for all commercial aluminum alloys, including aluminum sheets, aluminum strips, castings or stamping parts. 4. Will not damage the surface of the plated parts. 5. This process does not contain cyanide, environmental protection and safety.
