Advantages of using Limeda BK-10 brightening additive:

1. The electrolyte has a high covering and dissipation capacity
2. Galvanising process with Limeda BK is stable and easy to control
3. Economical consumption of no more than 2 ml/m2 per 1 µm
4. Brightening additive BK-10 and other components do not have complexing properties, which greatly facilitates the process of effluent neutralisation
5. The coating is easily passivated and phosphatised.

Approximate composition of the cadmium bath:

Limeda BK-10 – 20 (for drum) – 25 g ̸l (for hangers)

Cadmium oxide – 12-20 g ̸ l (for drum) – 15-22 g ̸ l (for hangers)

Sulphuric acid – 30-40 g/l (for drum) – 40-50 (for hangers)

Instructions for use of brightening additive for cadmium plating ‘Limeda BK-10’.

1. Cathodic current density for hangers is 1.5-2 A/dm2, for drum – 0.8-1.2 A/dm2
2. Bath temperature is 18-40 °C
3. Cadmium anodes to prevent accumulation of excessive cadmium are periodically replaced with insoluble anodes of ORTA brand.
4. Consumption of the additive is not more than 2 ml/m2 per 1 micron.

Electrolyte adjustment for input components is carried out according to the electrolyte analysis.
