stability
At present, the main industrial product is the low viscosity (1.5 ~ 2.5 Pa·s, 25℃) methylhyne epoxy resin. Hine epoxy resin has low viscosity and good process properties. Its viscosity is much lower than bisphenol A epoxy resin, and it has good process properties without diluent. Good thermal stability, high heat resistance, the insulation potting material can be used for more than 5000h at 180℃, and the service life is 40 years at 130℃; Good weather resistance, its coating in sunlight or ultraviolet exposure, not easy to yellow and powder, better than bisphenol A type epoxy resin and acrylic resin coating, its salt spray resistance, corrosion resistance is also very prominent; The electric performance is outstanding under high voltage and ultra-high voltage, especially with excellent arc resistance and leakage trace resistance; Strong polarity, low viscosity, so glass fiber, carbon fiber and a variety of fillers have good wetting ability and bonding, can be added without reducing the premise of the process, so that the coefficient of linear expansion and cost is reduced.
