Epoxy resins are generally refers to organic molecules containing two or more epoxy groups, except for a few, but they are not high relative molecular mass. The molecular structure of epoxy resin based on molecular chain containing epoxy groups for lively characteristics of epoxy groups may be at the end of the molecular chain, in the middle or into a ring structure. Since the molecular structure contains a lively epoxy groups, so that they can react with the cross-linking various types of curing agents to form insoluble polymer with 3 to mesh structure. Where the molecular structure of a polymer compound containing epoxy groups collectively referred to as an epoxy resin. Cured epoxy resin has excellent physical and chemical properties, its surface of the metal and non-metal material has excellent adhesion strength, good dielectric properties, variable set small shrinkage, good dimensional stability, high hardness, Flexibility is good, and most of the solvent on a stable base [1], which is widely used in various sectors of national defense, national economy, for pouring, dipping, laminating materials, adhesives, coatings and other purposes.
