Active amine photosensitizer QM-21C
QM-21C is a photoinitiator containing a tertiary amine structure. It exhibits a synergistic photoinitiator effect with hydrogen-abstracting photoinitiators, such as benzophenone, reducing oxygen inhibition, increasing the photocuring rate of UV systems, and lowering the amount of photoinitiator required in colored systems.
QM-21C is an economical version of QM-21, suitable for systems with no requirements on benzene content.
