What is Photoinitiator TPO?
Photoinitiator TPO (Diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide) is a highly efficient free radical photoinitiator that absorbs UV light and rapidly generates free radicals. These free radicals initiate polymerization of acrylate monomers and oligomers, converting liquid formulations into solid coatings or inks within seconds.
Unlike traditional photoinitiators, TPO offers excellent absorption in the longer UV wavelength region (approximately 350–420 nm), making it highly effective for thick coatings, pigmented systems, and UV-LED curing applications.
Its excellent penetration ability ensures complete curing even in opaque or highly filled formulations.
