Cyanide Free Alkaline Zinc Plating Chemicals Brightener High Throwing Power ZN-265

High Throwing Power Cyanide-free Alkaline Zinc Plating

ZN-265

ZN-265 alkaline zinc plating additive is a kind of brightener concentrated by a variety of polyamine compound. It can produce a smooth, bright, delicate and flexible zinc plating layer in alkaline non-cyanide zinc plating solution, and can completely replace the traditional cyanide zinc plating.

I. Properties

1, Electroplating can be carried out in a wide range of zinc metal content 5.5-18.5 g/L.

2, Can make the workpiece surface bright and decorative even the temperature up to 48 ℃.

3, Excellent covering capacity and dispersing ability in low current region, especially for some complex workpieces for rack plating. Such as pipes, fittings and computer shell.

4, Good dispersion capacity. High current density: low current density can reach 1.5. It can shorten the plating time and reach a minimum standard of coating thickness. Can improve the efficiency of the use of zinc.

5, Good tolerance with the impurities in the bath such as calcium, magnesium, iron, lead, cadmium and chromium.

6, It is suitable for low current density of barrel plating and wide current density range of rack plating.

7, Easy to accept various passivation post treatments.
