Passivates for Zinc-Nickel Deposits

SLOTOPAS ZNT 80

A trivalent transparent passivation process for electroplated zinc-nickel alloy coatings. The coating will have good corrosion protection which can be enhanced further with the addition of a sealant from the SLOTOFIN series.

SLOTOPAS ZN300

A trivalent black passivate process (which is Cobalt-, and Chromium VI-free) for electroplated zinc-nickel alloy coatings. When used in combination with post-dip NT10 or one of the SLOTOFIN series of sealants, it produces a uniform bright surface with excellent corrosion resistance.

SLOTOPAS ZNB60

A trivalent blue passivate process (which is Cobalt-, Fluoride-, and Chromium VI-free) for electroplated zinc-nickel alloy coatings. The coating will have good corrosion protection which can be enhanced further with the addition of a sealant from the SLOTOFIN series.

SLOTOPAS ZNC50

A trivalent colourful iridescent passivate process (which is Cobalt-free) for electroplated zinc-nickel alloy coatings. The coating will have good corrosion protection which can be enhanced further with the addition of a sealant from the SLOTOFIN series.

Sealants for Zinc-Nickel Deposits:

Sealant SLOTOFIN 10

SLOTOFIN 10 is a post treatment process for zinc-nickel deposits that have been passivated with a clear film.  The system is water based and can be applied by immersion or by spray.

Corrosion resistance is improved, and smudging after drying is reduced.

SLOTOFIN 10 does not contain chromium VI.

Sealant SLOTOFIN 40

Polymer-based and containing nanoscale silicon compounds, SLOTOFIN 40 is an alkaline process for the post treatment of passivated zinc and zinc alloy coatings.

This process enhances the corrosion protection and optical appearance while reducing the coating's sensitivity to fingerprinting.

Sealant SLOTOFIN 80

SLOTOFIN 80 contains inorganic polysilicates and substantially increases the corrosion protection of passivated zinc or zinc alloy coated parts.

An additional additive can be used to obtain a friction coefficient of µ=012±0.02.

Post-Dip Solution SLOTOPAS NT 10

A post treatment for zinc-nickel plated parts which have already been passivated.

SLOTOPAS NT 10 is an alternative to sealants on black passivated parts and reduces the sensitivity to touching, abrasion, and scratches while maintaining the necessary corrosion protection.
