Used primarily in epoxy resin systems to initiate and control the curing process, enabling the resin to harden into a durable, chemically resistant solid. Widely applied in coatings, adhesives, and composite materials for industries such as automotive, aerospace, and construction due to its ability to enhance mechanical strength and thermal stability. Commonly found in protective coatings for metal surfaces, flooring systems, and electrical insulation where long-term performance and resistance to environmental stress are critical. Also utilized in civil engineering for grouting and structural bonding, offering strong adhesion and low shrinkage during cure.
