Due to the accelerated growth of zinc-nickel in both the automotive and industrial markets, demand has been high for a colorless zinc-nickel passivate that delivers strong salt spray results. With a focus on meeting the needs of customers, COLDIP NI-Z CLEAR 250 passivate was developed to address these specific demands.
After thorough internal testing and analysis in both the R&D and service labs, the passivate went through test simulations on a pilot line and then into the first round of field testing. After an additional R&D phase to optimize the formulation based on the field data, the passivate is now in its second and final stage of field production testing in a number of plating shops.
- COLDIP NI-Z CLEAR 250 is a clear trivalent passivate for zinc-nickel plating. The passivate operates under mild conditions which allows minimal alloy loss during passivation and helps maintain nickel in the deposit.
- The easy-to-control single component system also offers stability to the bath life, another end-user benefit reported by Columbia’s technical field team.
- COLDIP NI-Z CLEAR 250 produces 250 hours of neutral salt spray to white corrosion without a sealer, exceeds 500 hours when top-coated and exceeds 1000 hours to first red rust.
- This unique, clear trivalent coating offers an extremely cost-effective alternative to high corrosion finishes.
We are currently qualifying two remaining trial locations to round out testing in our final phase.
