Used primarily as a multifunctional crosslinking agent in UV-curable and radiation-curable coatings, inks, and adhesives. Its four acrylate groups enable rapid polymerization upon exposure to UV light, resulting in highly crosslinked networks that provide excellent hardness, chemical resistance, and durability. Commonly found in industrial coatings for wood, metal, and plastics, where it enhances scratch resistance and adhesion. Also utilized in electronic encapsulants and 3D printing resins due to its ability to form rigid, dimensionally stable structures. Its high reactivity makes it suitable for formulations requiring fast curing and high performance under demanding conditions.
