Processes that are among the market leaders in the surface treatment industry.


With over 300 wet chemical products, Schlötter covers a very wide range of surface treatment processes. The associated processes, such as pre-treatment, passivation or sealing, are always part of the layer systems.
For the operation of these systems, which are more than 95% proprietary, we offer about 1000 different specialty chemicals.

· Acidic baths for decorative surfaces, electroforming and printed circuit board production.

With the help of nickel, it is not only possible to give a surface shine and finish. Technical properties such as good ductility and at the same time hardness can be obtained. Diffusion barriers can be created.

Zinc and zinc alloys
-For ferrous materials, electrolytic surface treatment with zinc or zinc alloy coatings is one of the most common and best ways to protect against corrosion and is often used in many industries.

-With the zinc processes (cyanide, alkaline-cyanide-free, slightly acidic with and without boric acid) and zinc core and zinc-nickel alloy processes (alkaline and slightly acidic), Schlötter covers the entire range of available processes.

-The Schlötter portfolio also contains a tin-zinc alloy, for which Schlötter offers a slightly acidic process.

-Passivations (based on trivalent chromium) protect zinc and zinc alloy layers and thus optimize the corrosion resistance of the coating systems.

-Different passivations under the SLOTOPAS brand provide transparent, blue, yellow, iridescent or black optics. Passivations can handle both thick or thin film passivation and with or without cobalt.

Sealer & post-dip
Finishing products for zinc and zinc alloys that give the zinc surface improved protection.

-Sealer, based on organic, water-soluble substances which after drying gives a thin, transparent film on the zinc surface and which, in addition to improved corrosion protection, also gives better resistance to fingerprints and mechanical wear.

Post-dip, based on water-soluble, inorganic salts which, after drying, give a thin, dense film consisting of dried inorganic salts.
