Used as a curing agent for epoxy resins, enhancing mechanical strength and thermal stability in coatings, adhesives, and composite materials. Commonly applied in aerospace, electronics, and structural adhesives due to its excellent cross-linking properties. Also employed in the synthesis of polyurethanes and rubber chemicals to improve durability and performance. Its reactivity makes it suitable for high-performance industrial applications requiring robust chemical and heat resistance. Handle with care due to its toxicity and potential to irritate skin and respiratory system.
