Used primarily as a curing agent in epoxy resin systems, it provides excellent thermal and mechanical properties. Its main application is in high-performance coatings, adhesives, and composite materials where durability and chemical resistance are critical. Due to its sterically hindered structure, it offers improved hydrolytic stability and reduced crystallization tendency, making it suitable for use in aerospace, automotive, and industrial tooling applications. It is also favored in elastomer formulations and potting compounds where extended working time and toughness are required.
