The cationic photocuring system is free from the interference of free oxygen, can quickly and completely initiate polymerization in the air, has small shrinkage during curing, forms a polymer with stronger adhesive force, is not easy to terminate the curing reaction, and is suitable for photocuring thick films and colored paints. Meanwhile, a hybrid photo-curing system capable of performing both radical polymerization and cationic polymerization is also receiving more and more attention from researchers.
