Used as a reactive diluent and curing agent in epoxy resin systems, enhancing flexibility and adhesion in coatings, adhesives, and composites. Its amine groups enable crosslinking with epoxies, improving chemical and heat resistance in cured networks. Commonly applied in industrial coatings, electrical encapsulation, and high-performance composite materials. Also serves as a surfactant and emulsifier in specialty formulations due to its polyether backbone, providing stability and dispersion in water-based systems.
