BRIGHT SILVER ELECTROLYTE FOR ELECTROFORMING For Noble Silver Hollow Jewellery ARGUNA® 621 EF is a silver electrolyte, especially to produce noble hollow jewellery. A layer with high thickness can be deposited on mandrels made conductive. The electrolyte works with wax and metal cores. It can be used within a wide current density range and is suitable for relatively high temperature ranges (40 degrees Celsius). Its good throwing power results in a uniform layer thickness distribution. The surfaces are bright and brilliant white, without blue cast and have a fineness of 99.9 percent silver. The layers can be easily reworked and soldered. Its hardness can be further increased with ARGUNA® 621 Brightener 3 up to approximately 185 HV. • Bright silver electrolyte for producing hollow jewellery on wax and metal cores • Suitable for relatively high temperature ranges (40 degrees Celsius) • Surfaces are brilliant white • Wide current density range • Very good throwing power, therefore, uniform thickness distribution
