Epoxy resin is:
Generally refers to organic compounds containing two or more epoxy groups in the molecule. Except for a few, their relative molecular mass is not high. The molecular structure of epoxy resin is characterized by active epoxy groups in the molecular chain. The epoxy groups can be located at the end, middle or in a cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can undergo cross-linking reactions with various types of curing agents to form insoluble polymers with a three-dimensional network structure. All polymer compounds containing epoxy groups in their molecular structure are collectively called epoxy resins. The cured epoxy resin has good physical and chemical properties. It has excellent bonding strength to the surface of metal and non-metal materials, good dielectric properties, small set shrinkage, good dimensional stability of the product, and high hardness. It has good flexibility and is stable to alkali and most solvents, so it is widely used in various sectors of national defense and national economy for pouring, impregnation, laminates, adhesives, coatings, etc.

Epoxy silicone resin:
Prepared from silanol and epoxy resin hydrolyzed by phenyl and methyl monomers through a special process, it combines the advantages of epoxy resin and silicone resin, has excellent heat resistance and anti-corrosion properties, and is oil-resistant and moisture-proof. , insulation, strong adhesion, and can be cured at low temperature. It is suitable for formulating various series of high-temperature resistant coatings, weather-resistant coatings, inner wall anti-corrosion coatings for high-temperature equipment, and H-class silicone insulating paint. The epoxy group as a functional group entering the polysiloxane side chain or end-capping can improve the surface activity and low-temperature flexibility of the polymer. The modified silicone resin has good adhesive properties, media resistance, water resistance, and atmospheric aging resistance. , and can be cured using amine curing agents and can be cured at room temperature, which greatly reduces the curing temperature of silicone resin. The modified resin can be used for a long time in the range of -60~200℃.
