Clear Cobalt-free Trivalent Passivate for Zinc and Zinc-Nickel (12-15% Ni) Deposits
FINIDIP 128 CF is a cobalt-free trivalent Chromium passivate for Zinc and Zinc-Nickel deposits (12-15% Ni). This formulation is characterized by excellent stability and produces a very consistent passivation result.
FINIDIP 128 CF is suitable for rack and barrel applications. In the case of barrel application it is recommended to apply a topcoat in a dip-spin centrifuge.
A sealer or topcoat can be applied to control the coefficient of friction and/or to increase the corrosion resistance
