The abstract of epoxy resin

Epoxy resin generally refers to molecules containing two or more epoxy groups of organic polymers, with the exception, but they are not high relative molecular mass. The molecular structure of epoxy resin is based on the molecular chain of epoxy groups with its lively characteristics of epoxy groups in the molecular chain can be the end of the middle or into the ring. Because the molecular structure of epoxy groups with lively, so that they can place various types of curing agents to form insoluble cross-linking reaction, does not melt with the three-network structure polymer.

Where the molecular structure of the polymer containing epoxy groups collectively referred to as epoxy resin. Cured epoxy resin has excellent physical and chemical properties, its surface metal and nonmetal materials, has excellent adhesive strength, good dielectric properties, variable setting shrinkage of small, products, good dimensional stability, high hardness, flexibility is better, and most of the solvent on the stability of alkali, which is widely used in national defense, national economic departments for pouring, dipping, laminating materials, adhesives, coatings and other uses.

Since 1958, China conducted a study of epoxy resin, and a very high speed into the industrial production has been booming throughout the country, in addition to the production of bisphenol A-epichlorohydrin common type epoxy resin, the also produces various types of new epoxy resin, in order to meet national defense construction and national economic sectors in urgent need of hair.
