Alkaline cyanide-free silvering process for direct plating of copper, copper alloys and nickel without the need for a silver shock bath | Product Finish

Silver is traditionally coated with toxic cyanide-based chemicals. Due to the extreme danger of cyanide to human health and the environment, the development of chemicals that do not contain silver cyanide is of paramount importance for silver plating. Discussed here is an alkali cyanide-free, water-based silver plating technology that can be applied directly to nickel, copper, and their alloys. Silver deposits have a perfect white color and better tarnish resistance than other non-cyanide silver processes. The silver is deposited entirely from dissolved silver anodes and the bath is very stable, maintaining a stable pH during coating and downtime periods. This new cyanide-free silver technology will be plated in brilliant silver making it ideal for electronic, industrial and decorative applications.

Electrolytic silver plating is one of the most important electroplating processes in decorative and electronic devices. Silver is traditionally coated with toxic cyanide-based chemicals. Due to the extreme danger of cyanide to human health and the environment, the development of chemicals that do not contain silver cyanide is of paramount importance for silver plating.Silver deposits have a perfect white color and better tarnish resistance than other non-cyanide silver processes. The new chemistry is very cost effective because the silver is completely anodized from the dissolved silver. The bath is very stable, the pH is well buffered and maintains a stable pH during sowing and downtime periods. This new cyanide-free silver technology will be plated in brilliant silver making it ideal for electronic, industrial and decorative applications.
Plated silver is traditionally used for decorative purposes such as silverware. Due to its excellent electrical properties, silver plating is widely used in switches, connectors, etc. in the electronics industry.
Since the first patent was issued in 1840, silver plating has usually been carried out in cyanide baths, which contain the most toxic chemical (cyanide) and pose a very high risk to human health and the environment. Therefore, attempts have been made to develop a cyanide-free coating system with excellent stability and environmental friendliness.
