Photocure TPO Photoinitiator TPO 75980-60-8 For uv 99%min
CAS NO. : 75980-60-8
Molecular formula : C22H21PO2
Appearance : light yellow crystal powderDue to its wide absorption range, its effective absorption peak is 350-400 nm, and its absorption is about 420 nm. Its absorption peak is longer than that of conventional initiators. After irradiation, two free radicals of benzoyl and phosphoryl groups can be formed. Can initiate polymerization, so light curing is fast,
It also has photo-bleaching effect, suitable for deep film thickening and yellowing of coating, low volatilization, suitable for water-based.
Used in white systems, it can be used in UV-curable coatings, printing inks, UV-curable adhesives, optical fiber coatings, photoresists, photopolymer plates, stereolithography resins, composite materials, dental fillers, etc.
