The manufacturer's reference condition for the specified plating rate is 3.5 volts using a platinum electrode.For immersion bath plating, we recommend starting with a moderate current density and adjusting the operating parameters according to the workpiece geometry and deposit quality.Suggested starting values for practical trials:ApplicationCurrent DensityBath plating – starting range0.5–1.0 A/dm²Bath plating – extended trial range1.0–1.5 A/dm²Pen platingDepending on electrode and contact areaBrush platingDepending on swab size and contact areaThese current density values are suggested practical trial ranges and are not manufacturer-confirmed operating specifications.The optimum current density depends on the workpiece surface area, electrode distance, bath movement, temperature and component geometry.Voltage alone does not determine current density. We therefore recommend using a regulated DC power supply with adjustable current control.Calculation example:For a workpiece surface area of 20 cm² and a current density of 0.01 A/cm²:20 cm² × 0.01 A/cm² = 0.20 AThe current should be monitored and controlled throughout the plating process to achieve consistent coating results.Suitable Electrodes – Platinum or Graphite?This gold electrolyte can be used with both platinum and graphite/carbon electrodes.Platinum Electrode – Our RecommendationExcellent chemical resistanceLong service lifeSuitable for professional electroplating applicationsReference electrode for the manufacturer's specified plating rateParticularly suitable for thicker gold depositsFor professional applications, especially when aiming for gold deposits exceeding 10 µm, we recommend using a suitable platinum electrode.Graphite / Carbon ElectrodeEconomical alternative to platinumSuitable for compatible electroplating applicationsInteresting option for larger electrode surfacesSuitable for various bath and selective plating applicationsImportant: We strongly advise against using stainless steel anodes for most of our electroplating processes.Gold Deposits Exceeding 10 µmThe manufacturer's specified standard maximum deposit thickness is approximately 5 µm.For applications requiring thicker gold coatings, deposits exceeding 10 µm can also be achieved under suitable process conditions.For these applications, we recommend using a platinum electrode and carefully controlling the current and other operating parameters.With increased deposit thickness, particular attention should be paid to uniform deposition, adhesion and electrolyte stability.The achievable thickness depends on the actual plating setup and must be verified under the intended operating conditions.Suitable ApplicationsThis 8 g/L gold electrolyte is suitable for:Jewellery and jewellery componentsWatches and watch componentsMetal fittings and decorative partsHigh-quality decorative objectsRestoration and repair gold platingElectrical contacts and metal componentsTechnical surface finishingIndividual and custom plating applicationsWorkpiece PreparationThe adhesion and quality of the gold deposit depend heavily on proper surface preparation.Before plating, the workpiece must be thoroughly cleaned, degreased and, where necessary, activated.Depending on the substrate material, such as stainless steel, copper, brass, silver or steel, a suitable intermediate layer or adhesion treatment may be required.Proper surface preparation is essential for achieving a durable, uniform and well-adhering gold coating.Storage and Shelf LifeStore the gold electrolyte protected from direct sunlight.The manufacturer's specified shelf life is one year when stored under suitable conditions.Betzmann Galvanik – Your Partner for Professional ElectroplatingBetzmann Galvanik supplies high-quality electroplating electrolytes and the corresponding equipment for professional surface finishing.Our product range includes:Gold, silver, platinum and rhodium electrolytesElectroplating equipment and regulated DC power suppliesGraphite and platinum electrodesAnodes and anode padsComplete systems for bath platingAccessories for pen plating and brush platingBenefit from our many years of experience in electroplating technology and our personal technical support.Order your 8 g/L Gold Electrolyte now and achieve high-quality 24-karat gold deposits with Betzmann Galvanik.
