[TPO Overview]


Photoinitiator TPO is a highly efficient free radical (1) type, highly efficient photoinitiator that absorbs over a long wavelength range. Due to its wide absorption range, its effective absorption peak is 350~
400nm, has been absorbed to about 420nm, its absorption peak is longer than the conventional initiator, after the light can produce two free radicals of benzoyl and phosphoryl groups, can initiate polymerization, so the light curing speed is fast, it also has light Bleaching, suitable for thick film deep curing and yellowing of coating, low volatility, suitable for water-based. Used in white systems, it can be used in UV-curable coatings, printing inks, UV-curable adhesives, optical fiber coatings, photoresists, photopolymer plates, stereolithography resins, composite materials, dental fillers, etc.


[Physical and chemical properties]


Properties: light yellow crystalline powder; melting point: 91-94 ° C, absorption wavelength: 273-370 nm; light curing speed is fast.

【characteristic】


Due to its wide absorption range, its effective absorption peak is 350~400nm, and it has been absorbed to about 420nm. Its absorption peak is longer than that of conventional initiators. After irradiation, two free radicals of benzoyl and phosphoryl groups can be formed. It can initiate polymerization, so it has fast photocuring speed. It also has photobleaching effect. It is suitable for deep film deepening and greening of coating. It has low volatilization and is suitable for water-based. Used in white systems, it can be used in UV-curable coatings, printing inks, UV-curable adhesives, optical fiber coatings, photoresists, photopolymer plates, stereolithography resins, composite materials, dental fillers, etc.


【use】


It is a photoinitiator mainly used for screen printing inks, lithographic inks, flexo inks, and wood coatings. TPO can be fully nationalized on white or high titanium white pigmented surfaces. Widely used in a variety of coatings, due to its excellent absorption properties, it is particularly suitable for screen printing inks, lithography, flexo inks, wood coatings. The coating does not yellow, the post-polymerization effect is low, and there is no residue. It can also be used for clear coatings and is especially suitable for products with low odor requirements. Used alone in unsaturated polyesters containing styrene systems, it has high initiation efficiency. For acrylate systems, especially colored systems, it is usually required to be used in combination with an amine or acrylamide gel, and compounded with other photoinitiators to achieve complete curing of the system, especially suitable for low yellowing, white systems and thick films. The curing of the layer. The photoinitiator TPO is used in combination with MOB240 or CBP393 to improve curing efficiency. It is the best extraction solvent for petroleum aromatics and is also used as a formylation reagent in the field of fine chemicals.
