Photoinitiator TPO powder CAS 75980-60-8
Photoinitiator TPO is a kind of highly efficient free radical (1) type photoinitiator with absorption in the long wavelength range.Because of the wide range of absorption, the effective absorption peak at 350 ~ 400 nm, soaking up to about 420 nm, its absorption peak Chemicalbook weaker than conventional initiator is long, light can generate benzoyl and phosphoryl two free radicals, can cause aggregation, so the light curing speed, it also has light bleaching, suitable for the characteristics of deep thick film and coating curing the same yellow, with low volatile, suitable for water-based.
