Used primarily as a multifunctional crosslinking agent in UV-curable and radiation-curable formulations. It enhances hardness, chemical resistance, and thermal stability of coatings, inks, and adhesives. Commonly found in industrial coatings for wood, metal, and plastics due to its fast curing and durable finish. Also utilized in printing inks, especially for flexible packaging, where it improves adhesion and scratch resistance. In electronics, it serves as a reactive diluent in encapsulants and conformal coatings. Its high functionality supports rapid polymerization, making it ideal for 3D printing resins and dental composites. Additionally, used in fiber treatment and textile finishes to improve strength and resilience.
