The process is distinguished by its non-toxicity, stability, economy and ease of operation. ZN-418 process has an unusually good brighteness range, comparable to conventional cyanide zinc plating. Deposits can be trated in clear chromate conversion coating dips to give a final blue bright finish, or full color passivation.
Deposits meet the salt spray requirements or federal sep.
Add caustic soda and zinc oxide and thoroughly mix. Fill with water to balance of the tank and allow the solution to cool. Add 418-Brightener, carrier and purifier and thoroughly mix. Since most of the zinc oxides are impure, an 8 hour session of dummying is required to purify the solution in order to obtain maximum brightness. The bath is now ready for operation.
