Widely used as a curing agent in epoxy resins, enhancing their mechanical properties and chemical resistance, making them suitable for coatings, adhesives, and composites. It serves as a chelating agent in water treatment processes, effectively binding and removing metal ions to prevent scale formation and corrosion. In the production of lubricants and fuel additives, it acts as a dispersant, improving performance and longevity. Additionally, it is utilized in the synthesis of surfactants and corrosion inhibitors, offering protective benefits in industrial applications. In the oil and gas industry, it functions as an absorbent for acid gases such as carbon dioxide and hydrogen sulfide in natural gas processing. Its role in the manufacture of paper and textiles includes improving wet strength and dye fixation.
