Yellow or Clear Zinc Chromate Coatings

Yellow and clear, sometimes called "white", essentially perform the same function as a superior corrosion inhibitor for your metal parts. The deposit is a pleasing finish in itself, however it is also an excellent base for paint.

 

Our zinc and chromate finishes are RoHS compatible

"Yellow zinc plating" means zinc plating followed by a yellow chromate conversion coating. The process may be done in plating barrels or by racking the individual parts, and usually involves cleaning, activating, zinc plating, 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 (as shown below) still offer good protection 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.
