UV resin, short for ultraviolet resin, is a type of resin that cures (hardens) when exposed to ultraviolet light. Unlike traditional resins that require hours to cure, UV resin hardens in a matter of minutes when exposed to UV light sources such as sunlight or UV lamps.

UV-curing resins are materials that are polymerized and cured in a short time by the energy radiated from ultraviolet irradiation devices. These are especially used as industrial materials for sealing, bonding, and coating.

The definition of UV (ultraviolet) curable resins is a product in which monomers, oligomers, etc. are solidified through a chain polymerization reaction by ultraviolet rays.

UV resin is a class of liquid resin that is specifically designed to cure with UV light. It usually contains aphotoinitiator, which is a chemical compound that absorbs UV radiation and triggers the hardening process.

UV resin is a synthetic resin that is famous for its quick-curing abilities under UV light. These resins do not require any mixing prior to application and can be worked with for any length of time, as they will only harden when placed under a specialized UV lamp.
