Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide(PI) is a key component of photocurable materials, which plays a decisive role in the photocuring speed of photocurable materials. A PI is a substance that can absorb radiation energy, undergo photochemical changes after excitation, and produce active intermediates (free radicals or cations) with the ability to initiate polymerization. Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide can be divided into ultraviolet initiators (absorbing ultraviolet 250 ~ 420nm) and visible light initiators (absorbing visible light 400 ~ 700nm) because of the difference in attracting radiation energy. Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide can be divided into two categories: free radical photoinitiators and cationic photoinitiators because of the different active intermediates produced. Free radical PI can be divided into two types: cracking photoinitiators and hydrogen robbing photoinitiators because of their different mechanisms of producing free radicals. At present, the main technology of photocuring is ultraviolet curing, and the photoinitiator used is ultraviolet initiator.
