VP Finish’s Zinc Plating is widely used to impart a brilliant sacrificial finish to facilitate a general degree of corrosion resistance and is also an excellent base layer for paint adhesion. 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.

Chromates & Sealers
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 (Blue) Chromate that provides a high level of corrosion protection. Our Yellow Chromate is also requested when corrosion protection of the Zinc Plating base layer is required in accordance with various industrial specifications. When a black finish is desired, our Black Zinc Chromate provide a deep iridescent black for both corrosion resistance and aesthetic purposes. In addition, when any of the our chromates are coupled with our Chromate Sealer, corrosion resistance is tremendously increased. Our various chromates provide different levels of corrosion resistance and some are RoHS compliant while others are not:
|Clear (Blue) Chromate
|Chromate + Sealer
*RoHS Compliance is valid only for Chromate Sealer over Standard Clear (Blue) Chromate
The following are just some of the machined part substrates we can successfully deposit our Zinc Plating on:
- Stainless Steel
- Brass and Copper Alloys
- Beryllium Copper
- Cast Iron
- Commercial Grade
- Commercial Grade with Certification (RoHS)
- Specification Grade with Certification
NOTE: Our Zinc Plating as well as our Standard Clear (Blue) Chromate are RoHS compliant coatings.
The following are only some of the more commonly requested Zinc Plating specifications we can certify to:
