Yellow Passivate will produce a yellow colored, iridescent chromate conversion coating on zinc or cadmium.
The film formed has excellent corrosion resistance and will meet all specifications calling for a yellow chromate which will withstand 140 hours salt spray. Zinc plated parts with a minimum thickness of zinc of 10 microns should withstand salt spray testing ranging from 250 hours to 500 hours before the appearance of red rust.
Yellow Passivate films also make an excellent base for the bonding of organic finishes.
