Used as a crosslinking agent in polymer chemistry, particularly in the formulation of specialty resins and coatings. Its aziridine groups readily react with carboxylic acids and other active hydrogen-containing functional groups, enabling efficient curing at ambient or elevated temperatures. Commonly applied in adhesives, sealants, and epoxy systems where enhanced chemical resistance, mechanical strength, and thermal stability are required. Also utilized in the development of advanced composite materials and as a modifier in radiation-curable systems due to its multifunctional reactivity.
