Used as a photoinitiator in advanced polymerization processes, particularly in UV-curable inks, coatings, and adhesives. Its fluorinated pyridine groups enhance light absorption in the near-UV range, allowing efficient radical generation under mild irradiation conditions. This makes it suitable for applications requiring low-energy curing, such as in electronics encapsulation and dental materials, where deep curing and minimal yellowing are critical. Additionally, its thermal stability and solubility in polar organic solvents support formulation in solvent-based and 100% solids systems.
