Product Name: Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide
Other Name: Photoinitiator TPO
CAS No.: 75980-60-8
Photoinitiator CAS 75980-60-8(TPO) has an absorption wavelength of 273-370 nm, and it has a wide absorption range. The effective absorption peak is 350-400 nm and the highest value is 420 nm.
In the visible light region, there is strong absorption at the 380nm-400nm wavelength, and the absorption curve can even extend to the visible region of 480nm.
The absorption peak of Photoinitiator CAS 75980-60-8(TPO) is longer than conventional photoinitiators. After the light, two radicals of benzoyl and phosphoryl groups are formed, and since they all have a polymerization function, the photocuring speed is fast.
