EPA chemical substance information Phosphineoxide,diphenyl(2,4,6-trimethylbenzoyl)-(75980-60-8)
Application field
It is mostly used in white systems, and can be used in UV curing coatings, printing inks, UV curing adhesives, optical fiber coatings, photoresist, photopolymerization printing plates, stereolithographic resins, composite materials, tooth fillings, etc.
The photoinitiator TPO is a highly effective free radical (1) type, which absorbs in the long wavelength range. Due to its wide absorption range, its effective absorption peak is 350-400nm, and its absorption is always about 420nm. Its absorption Chemicalbook peak is longer than conventional initiators, and it can generate benzoyl and phosphoryl after light exposure. It can initiate polymerization, so the photocuring speed is fast. It also has photobleaching effect. It is suitable for deep curing of thick film and the coating does not turn yellow. It has low volatility and is suitable for water-based.
