Our blue chromate concentrate produces a true blue conversion coating on zinc plated items. It is a single dip blue trivalent chromate that offers high salt spray resistance for up to 130 hours to white rust corrosion, and 160-200 hours to red rust corrosion. No additional topcoat is required to obtain this high degree of corrosion resistance. It produces a beautiful blue trivalent chromate to meet automotive and all other industrial standards.
