Used primarily as a crosslinking agent in polymer chemistry, this compound enhances the mechanical and thermal stability of coatings, adhesives, and composite materials. Its aziridine groups readily react with carboxylic acid, hydroxyl, and amine functionalities, enabling efficient network formation in epoxy, acrylic, and polyester resins. Commonly applied in specialty coatings where durability and chemical resistance are critical, such as in electronic encapsulants and industrial finishes. It also finds use in modifying resins for 3D printing due to its ability to promote rapid curing under mild conditions.
