Actual results may vary depending on the workpiece, pretreatment, current distribution, temperature, agitation and plating method.Operating Parameters for Tank PlatingCurrent DensityThe specified reference current density is 0.01 A/cm², with a recommended range of 0.008–0.012 A/cm².The appropriate current density depends on the geometry of the workpiece, its effective surface area and the conditions within the bath. Unsuitable or excessive operating values may adversely affect the quality of the gold coating.TemperatureThe specified operating temperature range is 18–40 °C. The reference deposition rate is based on a temperature of 20 °C with low agitation.Temperature affects the deposition rate and the behaviour of the electrolyte. For reproducible results, operating conditions should be kept as consistent as possible.pH ValueThe specified pH range is 4.3–4.5. The pH should be maintained within the intended operating range. Any adjustment must follow a procedure specifically approved for this product.Deposition Rate and Coating ThicknessAt a current density of 0.01 A/cm², a temperature of 20 °C and low agitation, the specified deposition rate is approximately 0.15 µm/min.The specified maximum coating thickness is 4 µm. The actual achievable thickness depends on the operating conditions and the condition of the electrolyte.Important: These reference values do not automatically apply to brush plating. With pen plating, the actual current density and coating results must be assessed under the specific application conditions.Application in Brush Plating and Pen PlatingIn brush plating, electrolyte is transferred to the surface being coated using a suitable electrode and an electrolyte-saturated tampon or applicator. This method is particularly useful for localised gold plating and repair work where the entire workpiece cannot or should not be immersed in a plating bath.Use of this electrolyte in a brush plating system is conditional on its suitability for the specific equipment and operating method being confirmed.Required EquipmentSuitable brush plating or pen plating systemGraphite or platinum electrode compatible with the electrolyteAppropriate tampon or electrode coveringGold electrolyte containing 4 g/L goldSuitable DC power supplyPersonal protective equipment as specified in the Safety Data SheetApplication Instructions1. Prepare the workpieceThoroughly clean and degrease the surface. Depending on the base material and coating system, suitable activation may be necessary. The preparation procedure must be appropriate for the substrate and the plating process.2. Prepare the electrode and tamponUse a graphite or platinum electrode only if it is compatible with the electrolyte and the equipment. Wet the appropriate tampon with the electrolyte in accordance with the equipment manufacturer's instructions. The tampon must remain sufficiently moist during application without dripping uncontrollably.3. Check the electrical connectionsIn conventional electroplating, the workpiece is normally connected as the cathode to the negative terminal, while the suitable working electrode is connected to the positive terminal. The correct configuration must be confirmed against the operating instructions for the specific equipment and its approval for this electrolyte.4. Set the voltageA voltage starting at 4 V may be considered only if it is approved for the particular brush plating system and this electrolyte. Voltage is not a universal operating setpoint. The actual current and current density depend, among other factors, on the contact area, pressure, tampon wetting and electrical resistance.5. Apply the gold coatingMove the wetted tampon evenly across the prepared surface. Maintain consistent movement, adequate wetting and stable electrical contact. Do not allow the tampon to dry out. Determine the appropriate operating values in accordance with the equipment manufacturer's instructions and the requirements of the specific application.6. Inspect the resultCheck the coating for uniformity and adhesion. The achievable coating thickness and deposition rate may differ from those obtained with conventional tank plating.Important Notes on Brush PlatingThe reference deposition rate of 0.15 µm/min at 0.01 A/cm² must not be transferred directly to brush plating without verification. The stated maximum coating thickness and coating quality must also be assessed under the actual application conditions.Graphite and platinum electrodes may only be used if they are compatible with the electrolyte and the system being used.Gold Replenishment and Bath MaintenanceDuring electroplating, gold is deposited from the electrolyte. As the bath is used, the available gold concentration decreases. A suitable gold replenisher specified to contain 16 g/L gold is intended for replenishing the gold consumed.The required replenishment depends on the actual gold consumption, bath volume and condition of the electrolyte. The following figures illustrate the calculation of gold turnovers and theoretical gold consumption.Calculating Gold TurnoversOne litre of fresh electrolyte containing 4 g/L gold initially contains 4 g of gold.Gold turnoversTheoretical gold consumptionGold replenisher containing 16 g/L1 turnover4 g gold250 ml5 turnovers20 g gold1,250 ml6 turnovers24 g gold1,500 mlThe table refers to one litre of starting electrolyte and the calculated replenishment volume required to replace the corresponding amount of gold. It does not replace an assessment of the actual bath concentration or condition. Replenishment must be based on an appropriate calculation and take the liquid volume into account.The recommended maximum bath life is approximately 5–6 gold turnovers. This is a guideline, not a guarantee that the bath will maintain consistent performance throughout this period.Evaporation and Liquid LossesEvaporation can affect the liquid level and concentration of the bath. According to the available product information, evaporation losses should be compensated for at the end of the working day using deionised water, restoring the original liquid level.Not all liquid losses are caused by evaporation. If electrolyte is carried out of the bath on workpieces, tampons or equipment, both liquid and dissolved gold are lost. These losses must be taken into account when maintaining the bath.Minimising Gold Losses Through Drag-OutDuring tank plating, allow coated workpieces to drain above the bath so that adhering gold-bearing electrolyte can return to the bath. This helps reduce gold losses caused by drag-out.With brush plating, controlled wetting and careful handling of the electrolyte are also important. Spilled or contaminated solution must not be returned to the bath indiscriminately.Crystallisation in a Nearly Exhausted BathAccording to the available information, potassium salts may crystallise when the bath is nearing exhaustion. Crystallisation indicates that the condition of the bath should be checked.Do not simply add water or replenisher and continue working. Determine the cause in accordance with the product-specific instructions and the Safety Data Sheet.Deposited Gold CoatingThe following values are specified for the deposited gold coating:Gold content: 99.9%Hardness: 190–210 HVDensity: 19.3 g/cm³Internal stress: MediumThe actual coating quality depends on workpiece preparation, current conditions, electrolyte condition and operating parameters.Storage and Shelf LifeSpecified shelf life: 1 yearProtect from direct sunlightKeep the container closed in accordance with the manufacturer's instructionsFollow the Safety Data Sheet and product labellingPrevent access by unauthorised personsSafety InformationThis product contains 0.15% potassium cyanide and requires knowledgeable and safe handling.Read the current Safety Data Sheet in full before use.Ensure suitable personal protective equipment and an appropriate workplace are available.Avoid contact with skin and eyes and do not swallow the product.Ensure suitable ventilation and safe handling procedures.Never mix with acids, acidic cleaners or other incompatible chemicals.
