Post Dip FT 190 Chemical

POST-DIPs FT 190 is a specially formulated liquid concentrate improving aspect, brightness and corrosion resistance of trivalent passivation films on Zinc and Zinc alloy deposits.

It is particularly suitable for black trivalent passivation by barrel or rack plating. If the control of coefficient of friction is required, it is also possible to apply a FINIGARD top-coat to improve the corrosion resistance.

When applied as a post treatment, parts processed with POSTDIP FT-190 will exhibit a glossy black finish and will provide greater than 120 hours to white corrosion when tested according to DIN EN ISO 9227 or ASTM B117.

For best results, POSTDIP FT-190 should be applied to a LANTHANE or FINIDIP trivalent black passivate and or zinc alloy deposit.
