VP Finish’s Zinc Plating is widely used to impart a brilliant sacrificial finish while also providing a general degree of corrosion resistance. It is often a first choice in cost-conscious applications where affordability is a concern. Our zinc chloride based electrolytic process deposits a single layer of zinc on many metal substrates. Our Zinc Plating is also often used as an excellent base layer for paint adhesion.

With the addition of one of our supplemental Chromates, the corrosion resistance of our Zinc Plating is significantly improved. The most typically requested chromate is our Standard Clear Chromate that provides a general level of corrosion protections. Yellow Chromates are requested when increased corrosion protection of the Zinc Plating base layer is required. When a black finish is desired, our Black Zinc Chromate provide a deep iridescent black for both corrosion and aesthetic purposes and our Olive Drab Chromate is often requested in military applications. Our various chromates provide different levels of corrosion resistance and some are RoHS compliant while others are not:
With the addition of one of our supplemental Chromates, the corrosion resistance of our Cadmium Plating is further improved. Our various chromates provide different levels of corrosion resistance:
|Standard Clear (Blue) Chromate
|Standard Yellow Chromate
|RoHS Yellow Chromate
