Zinc and zinc alloy deposits offer protection to ferrous materials against corrosion and are widely used in many industries. Zinc creates a barrier which acts as a thin sacrificial coating and therefore protects the substrate while Zinc Nickel increases the level of corrosion resistance and is widely used in the automotive industry.
With a wide range of zinc processes (cyanide, alkaline-cyanide-free, weakly acidic with and without boric acid) as well as zinc-iron and zinc-nickel alloy processes (alkaline and weakly acidic), Schlötter provides a broad range of market leading processes. The portfolio also includes a tin-zinc alloy for which Schlötter offers a weakly acidic process.
cathodic corrosion protection (CRC) in the automotive industry, aviation and fasteners.
Weak acidic fluoride-free electrolyte for the deposition of matt to semi-bright coatings. Excellent protection against red rust.
Alkaline/cyanide-free zinc-iron electrolyte which deposits matt coatings in the appearance of ROTOSIL 7
Alkaline/cyanide-free electrolyte for barrel application. Even steel types with poor starting behaviour can be plated very dependably due to the two-step process.
Alkaline/cyanide-free electrolyte. Special variant for barrel application. Coatings can be black passivated.
Alkaline/cyanide-free electrolyte with a special variant for barrel application. High iron content for good results in a black passivating.
