Epoxy Resin

· Epoxy resin is a type of polymer with two or more epoxy groups in its molecular structure. The backbone structure consists of organic compounds such as aliphatic, alicyclic, or aromatic. This type of polymer can form thermosetting products through the reaction of the epoxy groups. Due to the presence of active epoxy groups in the molecule, they can undergo cross-linking reactions with various curing agents to form three-dimensional networked high polymers. There are numerous types of epoxy resins, and their molecular weights typically fall within the range of oligomers. To distinguish them from the cured products, they are sometimes specifically referred to as epoxy resin oligomers.

Epoxy resin has strong adhesive properties, excellent mechanical performance, good chemical resistance, weather resistance, electrical insulation, and dimensional stability. It can be used as adhesives, coatings, casting materials, electrical insulation materials, and matrix resins for fiber-reinforced composite materials, and is widely applied in various industries such as aerospace, electrical electronics, mechanical manufacturing, construction, chemical corrosion prevention, ship transportation, etc. It is an indispensable and important basic material in all industrial fields.
