Used primarily as a multifunctional crosslinking agent in UV-curable formulations. Provides high reactivity and excellent curing speed in coatings, inks, and adhesives exposed to ultraviolet light. Imparts hardness, chemical resistance, and thermal stability to the cured material. Commonly found in industrial coatings for wood, metal, and plastics due to its ability to form dense polymer networks. Also used in electronic encapsulation and 3D printing resins where dimensional stability and durability are required.
