  • Applications

    Diglycidyl ether is predominantly used as an epoxy monomer and reactive diluent in epoxy resin formulations. In industry, it supports coatings, adhesives, sealants, and electronics encapsulation or potting due to its two reactive epoxide groups, which enable rapid crosslinking and durable films. It also serves as a chemical intermediate to synthesize specialty epoxy resins for fiber-reinforced composites and high-performance plastics, and as a crosslinking agent in various polymerization processes within plastics and coatings.
