Used primarily as a multifunctional crosslinking agent in UV-curable and radiation-curable coatings, inks, and adhesives. Its four acrylate groups enable rapid polymerization under UV light, resulting in highly crosslinked networks that provide excellent hardness, chemical resistance, scratch resistance, and durability. Commonly found in industrial coatings for wood, metal, and plastics, where fast curing and high performance are required. Also used in electronic encapsulants, 3D printing resins, and dental composites/cements due to its ability to form rigid, dimensionally stable structures with quick cure times and superior mechanical properties.
