Application of Photoinitiator TPO\2,4,6-Trimethylbenzoyldiphenylphosphine oxide\CAS NO.:75980-60-8:
1.TPO is mainly used for screen printing ink, lithographic printing ink, flexo printing ink, wood coatings.
2.TPO is used in UV curing type paint and ink.
3.TPO is the best extraction solvent for petroleum aromatics.The mixed solution of n-formyl morpholine and morpholine (1:1) is the extraction solvent of the acetone device.It is also used in fine chemical industry as a formylation reagent.
Properties of Photoinitiator TPO\2,4,6-Trimethylbenzoyldiphenylphosphine oxide\CAS NO.:75980-60-8:
The white crystal, a highly efficient free radical (1) type light, has a high-efficiency photoinitiator that absorbs over a long wavelength range, and it completely cures on a pigmented surface of white or high titanium dioxide. Due to its broad absorption range, its effective absorption peak is 350-400 nm, and its absorption is always around 420 nm. Its absorption peak is longer than conventional initiators, and it can generate two free radicals of benzoyl and phosphoryl after irradiation. Can initiate polymerization, so the photocuring speed, it also has a photobleaching effect, suitable for thick film deep curing and the coating does not yellow characteristics, with low volatility, suitable for water-based.
|Appearance||Slight Yellow powder|
|Abosorption wavelength||273, 370nm|
