White Palladium Electrolyte 10 g/L – Electroplate Palladium

White Palladium Electrolyte 10 g/L BMG-101M – High-Quality Palladium Plating for Bright, Silver-White Surfaces Electroplate White Palladium – for Decorative and Technical Applications The White Palladium Electrolyte BMG-101M with approx. 10 g/L palladium content is a professional electroplating solution for depositing bright, silver-white palladium coatings. The coating produces a bright metallic surface and is suitable both as a decorative final coating and as a nickel-free barrier and diffusion layer between copper or copper alloys and gold. Palladium is particularly suitable for applications requiring a high-quality, durable and nickel-free surface, including jewellery, watches, electronic components and precision parts. Your Advantages at a Glance Approx. 10 g/L palladium Very bright, silver-white metallic appearance High-quality decorative palladium coating Nickel-free barrier layer between copper/copper alloys and gold High corrosion resistance Low porosity Palladium is significantly more resistant to tarnishing than silver Suitable for jewellery, watches and technical components Also suitable for electrical contacts Solderable palladium coating High coating hardness of approx. 488 HV Suitable for professional electroplating applications What Is White Palladium Used For? The White Palladium Electrolyte is ideally suited for: Bright, silver-white palladium coatings Decorative metal surfaces Jewellery and jewellery components Watches and accessories Electronic components Electrical contacts Precision parts Corrosion protection Nickel-free coating systems Barrier layers before gold plating Preparation for subsequent precious-metal coatings Palladium provides a high-quality surface and, compared with silver, offers significantly better resistance to tarnishing. Palladium as a Barrier Layer Before Gold Plating One particularly important application is the use of palladium as a barrier layer before subsequent gold plating. A typical multilayer coating system may consist of: Base material → Copper → Palladium → Gold The palladium layer separates the base material from the gold coating and acts as a barrier and diffusion layer. This can help prevent unwanted interaction between the individual metal layers and allows a high-quality and durable gold coating to be produced. How Does Palladium Electroplating Work? During electroplating, palladium ions contained in the electrolyte are deposited onto the workpiece as metallic palladium using direct current. 1. Preparation Thoroughly clean and degrease the workpiece. 2. Electrical Connection Connect the workpiece as the cathode (negative pole). 3. Palladium Deposition The electrical current reduces the palladium ions at the workpiece surface, depositing metallic palladium. 4. Post-Treatment After plating, thoroughly rinse the workpiece with clean water and dry it. Suitable Base Materials The electrolyte can be used on appropriately prepared surfaces of various metals, including: Copper Brass Nickel Silver Gold Suitable dechromed surfaces The required pretreatment depends on the specific base material. For optimum adhesion, the surface must be clean, grease-free and properly activated.

Application Instructions Preparation Thoroughly clean and degrease the workpiece. Residues of oil, grease, polishing compounds and dirt can negatively affect adhesion and coating quality. Electroplating Heat the electrolyte to the recommended working temperature of 48–52 °C. Connect the workpiece as the cathode and set the recommended voltage. Gentle movement of the electrolyte can help produce a more uniform coating. Post-Treatment After plating, thoroughly rinse the workpiece with clean water and dry it. If required, the surface can subsequently be lightly polished to further enhance the appearance. White Palladium for Jewellery and Skin Contact Palladium is particularly suitable for applications where a nickel-free surface is desired. The bright, silver-white appearance makes the electrolyte suitable for: Rings Chains Pendants Bracelets Watches Jewellery components High-quality accessories White Palladium for Technical Applications In addition to its decorative applications, palladium also offers interesting technical properties. The coating can be used for: Electrical contacts Electronic components Precision parts Technical components Corrosion protection Multilayer precious-metal coating systems The combination of high hardness, corrosion resistance and low porosity makes palladium a versatile coating metal. Practical Tips for Optimum Results ✔ Thoroughly clean and degrease the workpiece. ✔ Prepare the surface according to the base material. ✔ Use a clean platinum or graphite anode. ✔ Heat the electrolyte to 48–52 °C. ✔ Keep the electrode distance as constant as possible. ✔ Use only gentle bath movement. ✔ Thoroughly rinse after plating. ✔ If gold plating follows, process the clean palladium surface without unnecessary delay. Safety Information The electrolyte is classified as irritating. H315: Causes skin irritation. H319: Causes serious eye irritation. H412: Harmful to aquatic life with long-lasting effects. When handling: Wear protective gloves Wear safety goggles or suitable face protection Wear appropriate protective clothing Avoid contact with skin and eyes Do not eat, drink or smoke while handling Work in a well-ventilated area Follow the Safety Data Sheet Dispose of the product and residues according to local regulations Available Sizes The White Palladium Electrolyte 10 g/L is available in various container sizes: 50 ml · 100 ml · 250 ml · 500 ml · 1 litre · 2 litres Product number: BMG-101M / BMG-101 White Palladium 10 g/L from Betzmann Galvanik The White Palladium Electrolyte BMG-101M with 10 g/L palladium is a high-performance solution for producing high-quality, bright and durable palladium coatings.
