Electroplating
Zinc & Zinc Alloys
Zinc electroplating is a technique that involves depositing a layer of zinc onto a metal surface through an electrochemical process. It is commonly used to provide corrosion resistance and improve the appearance of steel and iron-based materials. The zinc coating acts as a sacrificial layer, protecting the underlying metal from oxidation and extending its lifespan in various applications such as automotive parts, hardware, and galvanized steel structures.
Passivates & Topcoats
We offer a variety of zinc & zinc alloy finishes. As part of our zinc and zinc alloy finishing processes, we offer environmentally friendly passivates and topcoats that:
- Are available in clear, black and yellow colors. (Contact us for process availability)
- Can be applied over zinc or zinc alloys.
- Are free of chromium, nickel, mercury, and lead.
- Are non-electrically applied (no risk of hydrogen embrittlement).
- Can exceed 1,000 hours salt spray (DIN 50021 SS, ASTM B633).
- Have minimal coating thickness.
- Can withstand high temperatures (180C) without reducing corrosion protection or optical appearance.
- Come with a number of friction coefficient options.
- Are chemical resistant – fuel/brake fluid, etc.
