What are the curing methods of various UV adhesives?

UV glue is also an ultraviolet curing glue, and there is only one curing method, that is, ultraviolet irradiation curing. The curing principle of ultraviolet adhesive is that the photoinitiator (or photosensitizer) in ultraviolet curing material absorbs ultraviolet light under the irradiation of ultraviolet light, generates active free radicals or cations, and initiates the chemical reaction of monomer polymerization, crosslinking and grafting, so that the adhesive changes from liquid to solid in a few seconds.
