Schlötter has been developing electroless nickel products for many years and focuses on quality and efficiency in its processes. Electroless nickel coatings are not only wear-resistant, but also significantly harder than conventional electroplated nickel coatings and exceptionally chemically resistant. By choosing the right electrolyte system and optimizing the working parameters, the phosphorus content can be controlled according to requirements.
By adjusting the phosphorus content between two and twelve percent, the coating properties can be tailored precisely to individual requirements. A higher phosphorus content ("High-Phos") with over ten percent phosphorus, as with Slotonip NP 2090, not only improves the classic corrosion protection, but also ensures high resistance to a wide range of chemicals.
The electroless nickel bath Slotonip LP 1870, on the other hand, deposits layers with a low phosphorus content of 2-4% phosphorus ("low phosphorus"), allowing wear-resistant and hard nickel coatings to be applied. Due to the different composition and targeted post-processing of the nickel-phosphorus coatings, there are many possible uses in the various application areas.
The electroless nickel bath Slotonip NP 1150 ("Mid-Phos") is versatile and a real all-rounder. Also in the "Mid-Phos" range is the electroless nickel bath Slotonip NP 1220, which is operated at low working temperatures of 80 °C and is characterized by outstanding stability.
High bath stability and robustness are important characteristics of all processes in the Slotonip series.
Another highlight from the field of chemical nickel deposition is the newly developed stripper Slotonip NI 4020 for demetallizing baths and racks without the formation of nitrous gases.
In any case, environmental protection and sustainability play a special role at Schlötter in the development of new processes. For example, lead-free and cadmium-free alternatives are consistently used for stabilizers.
