cas 75980-60-8 irgacur tpo photoinitiator tpo

The photoinitiator TPO is a highly efficient free radical (1) type, which absorbs in the long wavelength range. Because of its wide absorption range, its effective absorption peak is 350-400nm, and the absorption is always about 420nm. Its absorption peak is longer than that of conventional initiators, and two free radicals, benzoyl and phosphoryl, can be generated after exposure to light. It can initiate polymerization, so the photocuring speed is fast. It also has photobleaching effect. It is suitable for thick film deep curing and the coating does not turn yellow. It has low volatility and is suitable for water-based.
