• Product description :

  1 It has high purity and light color and luster. It can be directly adjusted into all kinds of colorful epoxy resin products. 2 It has low viscosity. It has the characteristics like: good casting, embedment and impregnation technology. It can improve the performance of curing material and the affinity of lamination and basic material. 3 It has the characteristics like: stable performance, low freezing point and long using life. It can be stored for a long time at room temperature and easy for pipeline transportation. It is suitable for production automation and severe cold region. 4 It has small volatility and low toxicity, only 1/20 – 1/40 toxicity of the amine curing agent. Its irritation to human eyes and skin is small. 5 It has good dissolubility. This product can dissoluble with all epoxy resins. The mixing viscosity is low, meanwhile, has low pyrogenic effect and shrinkage during the heated curing process.

• Uses :

  It is widely used in electrical, electronic and casting industry. It is the main raw material of mutual inductor, insulated paint, high-voltage electrical apparatus, glass fiber reinforced plastics pipelines in oilfield and glass fiber reinforced plastics
