Molecular Structure:
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.
