LEGOR BROWN GOLD THICK PLATING SOLUTION, 1000ML, 1.5GM GOLD

The Legor Brown Gold Plating Solution contains 1.5grams of gold and requires a Platinised Titanium or Mixed Oxide Anode and needs moderate agitation. This solution is supplied in a ready to use form for bath plating.

Operating Data -

• Voltage - range - 0.5-3.5 - optimal - 2.5
• Current density (A/dm²) - range - 1.0-2.0 - optimal - 1.5
• Working Temperature - range - 35-45°c - optimal - 40°c
• Deposition rate at 1 A/dm² (µm/min) - 0.02

Legor Brown Gold Plating Solution preparation

GTBROWN is a ready-to-use plating bath at the concentration of 1.5 g/l of gold. No preparation is required while filling the working tank.

EQUIPMENT

Working vessel materials:

• Pyrex glass / PVC / polypropylene
• Power supply: DC current rectifier with low residual AC(<5%)
• Heating element
• Anode type: Platinized titanium [1.5-2.5 µm] or stainless steel

For larger bath volumes:

• Magnetic driven filter pumps with 5-15 µm cartridge (before use, boil and wash the cartridges with demineralized water for 3 hours to prevent organic contamination) 
• Amp/min counter

PRE TREATMENT

GTBROWN can be deposited directly onto Palladium, Nickel, and precious metal substrates. An intermediate deposit of Palladium or Nickle is required over Silver, and all alloys containing copper to prevent copper migration. An intermediate deposit or precious metal plating strike is necessary before depositing onto Tin, Lead, Zinc, Cadmium, Aluminum and Iron.

POST TREATMENT

In order to stabilize quickly the color deposited, immersion in hot water of the plated pieces (60-70°C for 30-60 seconds) is advised.

WATER PURITY

To prevent contamination of the bath both during its preparation and any subsequent replenishing operations, use demineralized water with a conductivity of less than 3 µS/cm (containing no traces of organic compounds, Chlorine, Silicon, or Boron).

BATH MAINTENANCE

It is necessary to maintain the solution at the optimum operating conditions through the addition of gold in form of gold potassium cyanide salt 58%. Ruthenium concentration is equal to 0.1-0.2 g/l with an optimum value of 0.15 g/l.

SUPPLEMENTARY INFORMATION

For maximum performance and in particular in terms of resulting color do not use an excessive agitation. A moderate agitation of the pieces to be plated will be sufficient. For larger volumes it is sufficient the use of a magnetic drive filter pump with a not too much high capacity.

SAFETY INFORMATION

Being an acidic solution, the electrolyte is an irritant to the skin, eyes and mucous membranes. Caution should be exercised when using the product, avoiding contact with the eyes and skin. Use gloves and safety goggles. Keep away from acid based chemicals. For further information please refer to the relative MSDS.
