Due to its wide absorption range, its effective absorption peak is 350 ~ 400nm, which has been absorbed to about 420nm. Its absorption chemicalbook peak is longer than that of conventional initiators. After illumination, it can generate benzoyl and phosphoryl radicals, which can initiate polymerization. Therefore, it has fast light curing speed. It also has photobleaching effect, which is suitable for deep curing of thick films and the characteristics of yellowing of coatings. It has low volatility and is suitable for water-based.The application field is mostly used in white system, which can be used in UV curing coating, printing ink, UV curing adhesive, optical fiber coating, photoresist, photopolymer printing plate, stereolithographic resin, composite material, tooth filler, etc.As photoinitiator, it is mainly used for silk screen printing ink, lithography ink, flexo printing ink and wood coating. TPO can be completely cured on the pigmented surface of white or high titanium dioxide. It is widely used in various coatings. Because of its excellent absorption performance, it is especially suitable for silk screen printing ink, lithography, flexo printing ink and wood coating. The coating does not turn yellow, the post polymerization effect is low, and there is no residue. It can also be used for transparent coating, especially for products with low odor requirements. In unsaturated polyester containing styrene system, chemicalbook has high initiation efficiency when used alone. Acrylate systems, especially colored systems, usually need to be used in combination with amine or acry lamide and other photoinitiators to achieve complete curing of the system, especially for low yellowing, white systems and thick film curing. The curing efficiency can be improved by using photoinitiator TPO in combination with mob240 or cbp393. It is the best extraction solvent for petroleum aromatics units and is also used as formylation reagent in fine chemical industry.Photoinitiator TPO is a highly efficient free radical (1) type photoinitiator with absorption in the long wavelength range. Because it has a wide absorption range, its effective absorption peak is 350-400nm, and it has been absorbed to about 420nm. Its absorption chemicalbook peak is longer than that of conventional initiators. After light irradiation, two free radicals, benzoyl and phosphoryl, can be generated, which can initiate polymerization. Therefore, it has a fast light curing speed. It also has a photobleaching effect, which is suitable for deep curing of thick films and the coating does not change yellow. It has low volatility and is suitable for water-based.
