Epoxy resin’s excellent physical, mechanical and electrical insulation properties, bonding properties with various materials, and flexibility in its use process are not available in other thermosetting plastics. Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials and injection molding materials, and is widely used in various fields.

Epoxy resin also has good adhesion to various metal materials such as aluminum, iron, and copper; non-metallic materials such as glass, wood, concrete, etc.; and thermosetting plastics such as phenolics and amino acids., unsaturated polyester, etc. all have excellent bonding properties, so they are called universal glue.
