B-21 Active Amine Photosensitive Promoter

B-21 is a photosensitive accelerator containing a tertiary amine structure. It is benzene-free and has low hue. It can produce photosensitive synergistic effects with hydrogen-abstracting photoinitiators such as benzophenone to reduce oxygen inhibition and improve the light intensity of the UV system. Cure rate, reduce the amount of photoinitiator in colored systems.
