Used as a reactive diluent in radiation-curable formulations, this compound helps reduce viscosity while maintaining low volatility. It is commonly employed in UV-curable coatings, inks, and adhesives due to its ability to enhance cure speed and improve flexibility and adhesion. Its multifunctional oxetane structure supports cationic polymerization, making it suitable for advanced printing technologies and electronic encapsulation where rapid curing and durability are required.
