Imported Premium Photoinitiator

In the light curing system, including UV glue, UV paint, UV ink, etc., after receiving or absorbing external energy, chemical changes occur in itself, which is decomposed into free radicals or cations, thus causing polymerization reaction.

Any substance that can produce free radicals and further initiate polymerization by light is referred to as a photoinitiator. [2] After some monomers are illuminated, absorbed photons form an excited state M* : M+ HV →M*; The excited active molecule produced free radical by homolysis: M*→R·+R '·, and then initiated monomer polymerization to form polymer.

Radiation curing technology is a new energy-saving and environment-friendly technology. Ultraviolet (UV) and ELECTRON beam (EB), infrared light, visible light, laser and chemical fluorescence irradiation curing can completely accord with the "5E" characteristics: Efficient, practical, Economical, Energy Saving and Environmental Friendly. Therefore, it is praised as "green technology". Photoinitiator is one of the important components of photocurable adhesives, which plays a decisive role in curing rate. After uv irradiation, the photoinitiator absorbs light energy and splits into 2 active radicals, which causes chain polymerization of photosensitive resin and active diluent, making the adhesive cross-linking cured. Its characteristics are fast, environmental protection and energy saving.
