Descriptions | The chemical name of photoinitiator 307 is 1- (biphenyl-4-yl) -2-methyl-2-morpholine-1-one, with the molecular formula C20H23NO2 and a molecular weight of 309.4. It is a light yellow to almost white powder with high purity (99%) and a melting point of approximately 160-170 ℃. Photoinitiator 307 is highly sensitive to oxygen and has a wide absorption range, with effective absorption peaks of 390 and 460 nm, and a wide photosensitive range Photoinitiator 307 is mainly used in the UV curing systems of unsaturated resins, such as those composed of acrylic resin prepolymers and some monomers with single or multiple functional groups. Under visible light or UV irradiation, photoinitiator 307 can initiate curing reactions of these resins. Due to its wide absorption range, photoinitiator 307 can be used in both light and dark color systems. Therefore, it is widely used in high-tech and high value-added fields such as UV coatings, UV inks, EB electronic inks, PCB inks, LED inks, dry films, UV adhesives, photoresists, photopolymerization plates, composite materials, tooth fillers, circuit pole inks, etc |
