TPOis an efficient free radical photoinitiator with absorption in a long wavelength range.Its effective absorption peak is 350-400nmand it always absorbs about 420nm. Its absorption peak is longer than that of the conventional initiator. After irradiation, two free radicals, benzoyl and phosphatidyl, can be formed, which can initiate polymerization. It is a photoinitiator for curing styrene-based unsaturatedpolyesters and acrylic resins. Its absorption in the long-wave region of the UV spectrum can fully cure even white paints and surfaces pigmented with TiO2. Such coatings are characterized by particularly low yellowing.TPO can also be used to cure clear coatings and is particularly suitable when low-odor products are desired.Recommended applications:screeninkswhitecoatings, flexoinkswoodcoatings, overprintvarnishesprintingplatesetc.The thermal stability of TPO is excellent. It is heated to 180℃ without chemical reaction and has good storage stability. info at hhochem. com
