Application

Di(4-t-butylphenyl)iodonium camphorsulfonate serves as a highly efficient photoacid generator (PAG) in UV-curable coatings and photoresists, enabling rapid polymerization under light exposure. Its thermal stability and low volatility make it suitable for high-temperature lithographic processes in semiconductor manufacturing. Researchers also employ it in cationic epoxy curing and click chemistry due to its strong Br?nsted acid release upon irradiation.
