UV, also known as shadowless adhesive, photosensitive adhesive, or ultraviolet curing adhesive, is a type of adhesive that can only be cured by ultraviolet light. It can be used as an adhesive and also as a binder for paints, coatings, inks, etc. UV is the abbreviation of Ultraviolet in English, which means ultraviolet light. Ultraviolet (UV) rays are invisible to the naked eye and represent a segment of electromagnetic radiation beyond visible light, with wavelengths ranging from 10 to 400 nanometers. The curing principle of UV curing adhesive is that the photoinitiator (or photosensitizer) in the UV curing material absorbs ultraviolet light under the irradiation of ultraviolet light to generate active free radicals or cations, which trigger the polymerization, crosslinking and grafting chemical reactions of monomers, and transform the adhesive from liquid to solid within seconds.

Prepolymer: 30-50% acrylate monomer: 40-60% photoinitiator: 1-6%

2. Additives: 0.2% to 1% (Additives can be added or not. It can be used as an adhesive and also as a binder for paints, coatings, inks, etc.)

3. Prepolymers include: epoxy acrylate, polyurethane acrylate, polyether acrylate, polyester acrylate, acrylic resin, etc

4. Monomers include: unifunctional (IBOA,IBOMA,HEMA, etc.), bifunctional (TPGDA,HDDA,DEGDA,NPGDA, etc.), trifunctional and multifunctional (TMPTA,PETA, etc.)

5. Initiators include: 1173,184,907, benzophenone, etc
