I. Product characteristics,

Electronic grade dicyandiamide is an upgraded product of ordinary dicyandiamide after deep purification and special processing. Its purity can reach more than 99.8%, and the metal ion content is strictly controlled at the ppm level (such as Na⁺, K⁺, Fe³⁺, etc. ≤5ppm), meeting the stringent requirements of high-end electronic applications such as semiconductors, copper-clad laminates (CCL), and multilayer ceramic capacitors (MLCC). With its stable molecular structure and high reactivity, it is an ideal raw material for synthesizing high-performance resins, electronic packaging materials, and special chemicals.

II. Main uses

1. Copper-clad laminate manufacturing: In the electronics industry's copper-clad laminate manufacturing, electronic grade dicyandiamide is used as an epoxy resin curing agent. Copper-clad laminates are the basic materials of printed circuit boards (PCBs), and their quality directly affects the performance of PCBs. Electronic grade dicyandiamide can cross-link and cure epoxy resins, improving the mechanical properties, electrical properties, and heat resistance of copper-clad laminates, ensuring that PCBs operate stably in various complex environments, and are widely used in various electronic products such as computers, mobile phones, and automotive electronics. For example, in the manufacture of motherboards for high-end smartphones, high-performance copper-clad laminates made with electronic grade dicyandiamide are indispensable, ensuring the stable operation and signal transmission of the internal circuits of the phone.

2. Inner coating film of food and beverage metal packaging: It can be used for the inner coating film of food and beverage metal packaging. In the field of food and beverage packaging, it is necessary to ensure both the good protective effect of the packaging material on the contents and food safety. The inner coating film made with electronic grade dicyandiamide can effectively prevent direct contact between metal and food and beverages, preventing metal ion migration into food, while also having good corrosion resistance and stability, extending the shelf life of food and beverages. For example, the inner coating of commonly used canned drinks may use materials related to electronic grade dicyandiamide.

3. High-grade non-toxic flame retardant: As a high-grade non-toxic flame retardant, electronic grade dicyandiamide is widely used in materials with high requirements for flame retardancy and environmental protection. For example, in the shell materials of electronic devices and building decoration materials, it can effectively improve the flame retardancy of materials and reduce the risk of fire without producing toxic and harmful substances. In the manufacture of shells for some smart home products, flame-retardant materials made with electronic grade dicyandiamide ensure product safety and meet environmental protection standards.

4. Semiconductor packaging materials

In chip packaging adhesives, its high purity characteristics can avoid the risk of circuit short circuits caused by impurity introduction, ensuring the long-term stability and signal transmission efficiency of the packaging materials.

5. Multilayer ceramic capacitors (MLCC)

Used in the synthesis of organic carriers for MLCC electrode slurries, it helps in the production of miniaturized, high-capacity capacitors, meeting the high-density integration requirements of electronic components for smartphones and new energy vehicles.

6. New energy battery materials

It plays a unique role in the research and development of lithium battery separator coatings or solid-state electrolytes, improving battery safety and cycle life.
