Technical tips		Premium mechanical properties (Tg temperature 8~10 degree higher).	Equal to "Hitachi chemical" HN-2200	Equal to "Hitachi chemical" HN-2200. But color sensitive applications, color constant after add accelerator (dielectric loss tangent lower than others).	Exceptional color properties for MTHPA (good optical properties, mainly used in the same industries as the MHHPA).	Equal to "Hitachi chemical" HN-2200

Characteristics:
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.
Main usage:
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 insulating bush.
Packing, Storage and transportation:
  220kg iron drum/ 1150kg IBC / 23000kg ISO tank.
This product's performance is stable. In the storage and transportation process, it should be sealed and avoid moisture. It should be stored in dry and ventilated warehouse. It can be stored one year at room temperature.
