Zinc Plating Processes
Corrosion protection is one of the fundamental tasks in electroplating technology. Zinc and zinc alloy processes from Schloetter offer a high-quality and cost-effective protection for functional components which are intrinsically linked with our post-treatments.

Alkaline Zinc Electrolytes
08016 Bright Zinc ZINCASLOT 50
Bright Zinc ZINCASLOT 50 is an alkaline, non-cyanide process for rack and barrel plating.
Features of Bright Zinc ZINCASLOT 50 are as follows:
- good adhesion of zinc layers
- high cathode current density range.
The zinc deposits are bright over a wide current density range, and can be easily chromated.
08101 Zinc ZINCASLOT ZA 1020
Zinc ZINCASLOT ZA 1020 is an alkaline, non-cyanide process suitable for both rack- and barrel plating.
Features of Zinc ZINCASLOT ZA 1020 are as follows:
- excellent metal distribution
- very good adhesion of zinc coatings
- high operating range with regard to the applicable current density
- good results in chromating and passivating
08801 Bright Zinc ZINCACYN 100
Bright Zinc ZINCACYN 100 is easy to handle and features high stability and high applicable cathode current densities. Its coatings are bright over a wide current density range and shows a good chromating behaviour, even if the bath temperature is slightly raised.
Bright Zinc ZINCACYN 100 can be operated in barrel and rack installations with either high or low cyanide levels, depending on the zinc concentration in the bath. The brightness is maintained by replenishment with a multi-component additive.
Weakly Acidic Zinc Electrolytes
08241 Bright Zinc SLOTANIT OT 1
Bright Zinc SLOTANIT OT 1 is a weak acidic bright zinc electrolyte for both rack and barrel Plating. The deposits produced are very bright, ductile and give excellent adhesion of chromated or passivated layers.
Depending on metal concentration, electrolyte temperature and chloride concentration SLOTANIT OT 1 may be operated with a high current range. At temperatures above 35 °C there could be a small reduction in brightness but this does not significantly affect the throwing power of the electrolyte.
The electrolyte is normally operated without ammonia, which makes effluent treatment easier. Ammonium salts may be used in the electrolyte but the ductility of the zinc deposit decreases as the concentration of ammonia increases, so concentrations of more than 10 g/l of ammonia should be avoided.
08253 Zinc SLOTANIT OT 1010
Zinc SLOTANIT OT 1010 is a weak acidic electrolyte for rack and barrel plating. Very bright coatings with excellent bright throwing power and ductility in combination with the possibility of good chromating and passivating are remarkable features of this process.
Depending on metal concentration, electrolyte temperature and chloride concentration, SLOTANIT OT 1010 may be operated in high current density range. A cloud point, even at a high salt content, isn’t normally expected, so high operating temperatures of up to 45 °C especially in barrel applications is not a problem.
