"Safe and Secure" Non-Cyanide Silver Plating Solution "Dine Silver" 2-2

Progress in the Development of Non-Cyan Silver Plating Solution 2

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).

To realize a sustainable society - Safe, secure, and wearable silver plating - Non-cyanide silver plating solution "Dine Silver"

basic information

**What is Cyan?** Cyan compounds include potassium cyanide (bitter almond) and sodium cyanide (soda cyanide), which are extremely toxic substances that can lead to death. They release toxic gases when heated. **Improving Corporate Image** In general society, influenced by media such as television, the association of "cyan" with "plating" has created a negative image of danger. Plating technology is a key technology that supports cutting-edge industries and is used in highly advanced fields. By eliminating cyan, the level of advancement increases, and the corporate image as an environmentally friendly, ecology-conscious company improves. This is particularly effective in global markets such as Europe and China.
