What kind of glue is uv glue?

Shading glue (uv glue) is also called photosensitive glue and UV curing glue. Shadow-less adhesive is a kind of adhesive that can only be cured by ultraviolet radiation. It can be used as an adhesive and glue for paint, coating and ink. UV is the abbreviation of ultraviolet, that is, ultraviolet ultraviolet (UV) is invisible to the naked eye, which is a section of electromagnetic radiation other than visible light, and its wavelength is in the range of1/kloc-0 ~ 400 nm. The curing principle of shadowless 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, initiates monomer polymerization and cross-linking chemical reactions, and makes the adhesive change from liquid to solid in a few seconds.
