Light curing mechanism

The UV light curing system is divided into a free radical system and a cationic system. The components of the curing mechanism of the two are different. The free radical system is excited by the photoinitiator by UV irradiation to generate free radicals, which initiates the polymerization and crosslinking of monomers and prepolymers; In the cationic system, a strong protonic acid is generated by irradiation of a cationic photoinitiator, which catalyzes addition polymerization and cures the resin.
