Shadowless glue (uv glue) is also known as photosensitive glue and ultraviolet curing glue. Shadowless glue is a type of adhesive that must be cured by ultraviolet light. It can be used as an adhesive or as a paint, coating, etc. Used for rubber materials such as ink.

UV is the abbreviation of English Ultraviolet Rays, that is, ultraviolet rays. To

Ultraviolet (UV) is invisible to the naked eye. It is a section of electromagnetic radiation other than visible light with a wavelength in the range of 10~400nm.

The curing principle of shadowless adhesive is that the photoinitiator (or photosensitizer) in the UV curing material absorbs ultraviolet light and generates active free radicals or cations, which initiates monomer polymerization and crosslinking chemical reactions, so that the adhesive is Change from liquid to solid within a few seconds.
