Used as a curing agent and crosslinking agent in epoxy resin systems, providing excellent mechanical strength, thermal stability, and chemical resistance. Commonly applied in high-performance coatings, adhesives, and composite materials for aerospace, automotive, and electronics industries. Its aliphatic structure contributes to improved flexibility and reduced brittleness in cured resins. Also utilized in specialty polymers and as an intermediate in synthesizing functional additives for polyurethanes and other advanced materials.
