Widely used as a curing agent for high-performance epoxy resins, enabling the formation of durable, heat-resistant networks. Commonly found in aerospace composites, electrical insulators, and structural adhesives due to its ability to enhance mechanical strength and thermal stability. Also employed in the synthesis of polyurethanes and specialty polymers where robust molecular architecture is required. Its aromatic amine structure contributes to excellent cross-linking density, making it suitable for coatings and encapsulants exposed to harsh environments.
