Used primarily in epoxy resin systems to initiate and control the curing process, enabling the formation of strong, durable, and chemically resistant coatings, adhesives, and composites. Widely applied in industrial maintenance coatings, marine and protective paints, civil engineering (such as concrete flooring and grouts), and electrical encapsulation due to excellent adhesion and mechanical strength. Also utilized in composite manufacturing for aerospace and wind energy sectors where high performance and reliability are critical. The curing action improves thermal and chemical resistance, making it ideal for harsh environments.
