Yellow or Clear Zinc Chromate Coatings

Yellow or clear zinc chromate coatings essentially perform the same function as a superior corrosion inhibitor for your metal parts. And while the deposit is a pleasing finish in itself; it is also an excellent base for painting.

The zinc chromate process, a protective coating technique that enhances corrosion resistance and provides a durable, clear or yellow-gold finish for metal surfaces. Ideal for aerospace, automotive, and industrial applications, this process ensures long-lasting protection and performance.

Only our clear zinc chromate finish is RoHS compatible.

“Yellow zinc plating” means zinc plating followed by a yellow chromate conversion coating.

The process is done by racking the individual parts, and usually involves cleaning, activating, zinc plating, applying the chromate conversion coating, and drying — with good rinsing between each stage. Each of these steps requires careful process control.

The yellow chromate is a yellowish, gold-like iridescent finish and has outstanding resistance to salt spray and other environmental factors.

Clear finishes still offer significant protection but with a lighter, natural colored finish. While there are minor durability differences between the two, we can advise you of those differences and help you choose the correct process for your requirements.
