Superiority
Photoinitiator 907 is a highly efficient UV photoinitiator used to initiate UV polymerization of unsaturated prepolymerization systems. Such as: acrylic resin and monofunctional and polyfunctional vinyl monomers.
The initiator molecules absorb light in the ultraviolet region (250-400 nm) or in the visible region (400-800 nm). After the direct or indirect absorption of light energy, the initiator molecules transition from the ground state to the excited singlet state. Reactively excite the triplet state; after excitation of the singlet or triplet undergoing single-molecule or double-molecule chemistry, active fragments are generated that can initiate the polymerization of the monomers. These active fragments can be radicals, cations, anions, and the like. According to different initiation mechanisms, photoinitiators can be divided into radical polymerization photoinitiators and cationic photoinitiators, of which radical polymerization photoinitiators are most widely used.
The high absorption characteristics of photoinitiator 907 make it particularly suitable for UV-curable inks and pigmented coatings. UV inks contain a relatively large amount of photoinitiators, and it is these photoinitiators that facilitate rapid drying of the ink during the printing process. These photoinitiators are not stable by themselves, and even in dark environments, dark reactions are prone to occur, resulting in the formation of individual ink gel nuclei, followed by a large area of gelation, especially when metal inks are preserved. Similar situation. Therefore, it is recommended that the ink pigments be stored separately from the binder. When used, stir and mix with large machines.
High-efficiency photoinitiators are used in UV-curing systems, which can prevent long-term yellowing and extended storage. An initiator that specifically targets pigmented UV-curing coatings, inks, and adhesive colored curing systems, and can be used with 184, ITX, and other initiators. Can be used in colored ink systems, paper/metal and plastic coatings and electronic inks. It can also be used as a UV absorber in cosmetics and other industries. It is recommended to add 2-6%.
