Mainly used as a curing agent for epoxy resins and as a raw material for polyester resins in coatings. It is primarily used in electrical and electronic fields, featuring low melting point, low viscosity when mixed with epoxy resins, good compatibility, long pot life, high heat resistance of cured products, excellent electrical properties, and good chemical resistance. It can be used for impregnation of electrical equipment coils and potting/encapsulation of electrical components, such as dry-type transformers, high-voltage switches, sensors, LEDs, digital tube packaging, etc.
