Epoxy resin means two or more epoxy group of organic polymers included by the molecule, barring a few exceptions, there are no high relative molecular mass in it. Epoxy resin based on the molecular structure of the molecular chain containing active epoxy group for its characteristics, epoxy groups can be located at the end of molecular chain, the middle or into the ring.
As the molecular structure contains active epoxy groups, so they can place a variety of types of curing agents to form insoluble cross-linking reaction does not melt with the three to the polymer network structure.

The normal manufacturing steps of Epoxy Resin as below:
1, Active hydride reaction with epichlorohydrin;
2, Hydrogen peroxide or peracid (eg peracetic acid) to liquid-phase oxidation of double bond;
3, Air oxidation of double bond compounds;
