Used primarily as a curing agent for epoxy resins, enhancing thermal stability, mechanical strength, bond integrity, and chemical resistance in products such as coatings, adhesives, and materials for electrical and electronics industries. It also functions as a chain extender and curing agent in polyurethane production, particularly in cast urethane systems requiring high strength and abrasion resistance. Additionally, it serves as an intermediate in the synthesis of dyes, corrosion inhibitors, and various polymers, including applications in automotive, aerospace, and industrial manufacturing.
