99% UV Absorbent Photoinitiator 907 CAS:71868-10-5

Application field: Photoinitiator 907 is a kind of high-efficiency ultraviolet photoinitiator, used to initiate the UV polymerization reaction of unsaturated prepolymerization system. Such as: acrylic resin and monofunctional and multifunctional vinyl monomers. The initiator molecule has a certain light absorption ability in the ultraviolet light region (250~400nm) or visible light region (400~800nm). After directly or indirectly absorbing light energy, the initiator molecule transitions from the ground state to the excited singlet state, and intersystem jumps. To excited triplet state; after the excited singlet state or triplet state undergoes single molecule or bimolecular chemistry, active fragments that can initiate monomer polymerization are generated. These active fragments can be free radicals, cations, anions, etc. According to different initiation mechanisms, photoinitiators can be divided into free radical polymerization photoinitiators and cationic photoinitiators, among which free radical polymerization photoinitiators are the most widely used. The unique high absorption characteristics of photoinitiator 907 make it especially suitable for UV curing oil Chemicalbook inks and colored coatings. UV ink contains a large amount of photoinitiators, it is these photoinitiators that promote the rapid drying of the ink during the printing process. These photoinitiators themselves are not stable. Even in a dark environment, dark reactions are very easy to occur, resulting in individual ink gelation nuclei, followed by large areas of gelation, especially when storing metallic inks. Similar situation. Therefore, it is recommended to store ink pigments and binders separately, and use large-scale machinery to stir and mix them when they are to be used. High-efficiency photoinitiator is used in UV curing system, which can make it non-yellowing for a long time and prolong storage. An initiator specially designed for colored curing systems of UV-curable coatings, inks and adhesives containing pigments. It can be used in conjunction with initiators such as 184 and ITX. It can be used in colored ink systems, paper/metal and plastic varnishes and electronic inks. It can also be used as an ultraviolet absorber in cosmetics and other industries. It is recommended to add 2-6%.
