B-21C Active Amine Photosensitive Promoter

B-21C is a photosensitive accelerator containing a tertiary amine structure. It can produce photosensitive synergistic effects with hydrogen abstraction photoinitiators such as benzophenone, reduce oxygen inhibition, increase the photocuring rate of UV systems, and reduce the temperature of colored systems. amount of photoinitiator. B-21C is an economical version of B-21, which has no requirement for benzene content.
