  • Applications

    1,3-Benzenedimethanamine, CAS 1477-55-0, is primarily used as a reactive diamine curing agent for epoxy resins, enabling the formation of high-temperature, chemically resistant networks in coatings, adhesives, and encapsulants. It is also used as a chain extender and crosslinker in polyurethane and polyurea formulations, improving hardness and durability of industrial coatings and sealants. As an industrial intermediate, it participates in the synthesis of high-performance polymers such as polyamides and polyimides, as well as in specialty resins for demanding applications. Additionally, MXDA is used as a building block in epoxy resin systems and thermoset resins for electronic materials and related adhesive formulations, with broad applicability across industrial chemicals and material sectors.
