Challenging the impossible: Non-cyanide silver plating solution! Successfully developed and commercialized for the first time in the world by Daiwa Chemical Research Institute. As the plating industry urgently seeks to develop plating baths that do not use cyanide compounds, non-cyanide plating solutions for zinc and copper were relatively quickly developed. However, silver plating was said to be impossible to achieve without cyanide, even within the industry. Daiwa Chemical Research Institute took on this difficult challenge and succeeded in 1989 in developing the world's first non-cyanide silver plating solution, "Dine Silver AG-PL30," which does not use any cyanide compounds, and brought it to practical use. For over 20 years after its development, the institute considered it its mission to eliminate the risk of toxic substance leakage during disasters from the plating industry and diligently continued research. As a result, they developed the "Dine Silver GPE Process," which allows for high-speed, high-current plating and has excellent coating ductility, establishing a system that can replace all types of cyanide silver plating baths. The term "Dine Silver GPE" stands for "Gentle to People and Environment," embodying the philosophy of considering the workability and safety of operators involved in plating while being environmentally friendly (free from RoHS-regulated substances).

■Safe and Secure Silver Plating Currently, the mainstream silver plating used in industrial applications is cyanide plating baths, which were invented in 1838 by G.R. Elkington in the UK. Since then, cyanide compounds have been used for about 180 years and are still widely utilized today. This is because cyanide forms very stable complexes with many metals and can create dense and uniform coatings, making it not only used for silver plating but also for zinc plating, copper plating, and gold plating for a long time. However, the strong toxicity of cyanide poses many issues regarding occupational safety and wastewater treatment, leading to the early development of "non-cyanide plating solutions" in the plating industry. *For more details, please refer to the related links below.*

Silver plating has been valued since ancient times for its unique hue and has been widely used in decorative items alongside gold. It is still utilized today in decorative accessories, tableware, medals, and more. Furthermore, silver boasts the best electrical and thermal conductivity among metals, a reflectivity close to 100% in the visible light spectrum, and excellent oxidation resistance, making it suitable for a wide range of applications including various lead frames, electrical contacts, and reflectors for functional plating. Plating processes involve the use of various chemicals, some of which include harmful substances like lead, mercury, and cadmium that can impact human health and the environment. Toxic cyanide compounds are also used in silver plating. Yamato Chemical Research Institute has developed the world's first practical "non-cyanide silver plating solution" that allows for the safe and secure use of silver's excellent properties without cyanide. This environmentally friendly non-cyanide plating solution from Yamato Chemical is called "Dine Silver." *For more details, please refer to the related links below.*
