Bonding Powder for Electronic Iron Powder Cores
Product Introduction:
This product is a thermosetting epoxy-modified bonding powder, formulated using special epoxy resin and functional curing agents. It features high reactivity, strong adhesion, high cross-link density, and excellent resistance to chemicals, solvents, as well as superior flexibility and impact resistance. The product offers outstanding physical, mechanical, and chemical properties. During the curing process, it has minimal shrinkage, resulting in a smooth and dense surface on the molded powder core. This overcomes the defects of polyethylene-based binders, and its superior characteristics determine the quality of the iron powder core.
Product Usage:
Special bonding agent for molding electronic soft magnetic iron powder cores.
Product Features:
- High mechanical strength: The surface of the molded components is smooth and dense. After curing, it has excellent adhesion to various metal powders, strong rigidity, good mechanical properties, and a high pass rate for finished products.
- Low shrinkage of the cured product: The cured product has excellent dimensional stability, reducing precision errors caused by shrinkage stress during the curing process.
- Excellent processing performance: It has good dispersibility and lubricity with metal powders, reducing friction between powders and molds during molding. The surface precision of the molded iron powder core is high, suitable for assembly line production.
- Excellent electrical properties: The cured product has a very high glass transition temperature and a wide operating temperature range, maintaining optimal stable electrical properties between -65°C and 110°C.
- Good dielectric properties: The cured components have excellent chemical and solvent resistance, withstanding organic chemical corrosion.
- Energy-saving and environmentally friendly: The curing temperature is low and fast. It can be cured using the baking temperature of external painting or powder coating, saving energy. It is a 100% solid component with no harmful substances and is an environmentally friendly product promoted by the state.
