BLUE CHROMATE

After preparing the part to accept the process, the part is simply dipped into a solution for a few minutes. The zinc & the chromate react to form the new colors. To improve those older zinc (pot metal) castings, plate with a fresh zinc plate before chromating.

Steel parts that have previously been plated with zinc can be chromated with no further pretreatment. Zinc alloy die cast parts may be surface activated by immersion in a weak acid. Full operating instructions are in the manual. The Blackener provides a deep black finish, similar to a Black Oxide, but with much better corrosion resistance

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.
Dip zinc plated parts at room temperature for 15-40 seconds. For best results, dry with hot air (150 deg F)
