Active amine photosensitizer

B-21C

Product features:

B-21C is a photoinitiator containing a tertiary amine structure, which can exhibit a synergistic photoinitiation effect when combined with hydrogen-abstraction-type photoinitiators—such as benzophenone—thereby reducing oxygen inhibition, enhancing the photocuring rate of UV systems, and lowering the dosage of photoinitiators in colored systems. B-21C is an economical version of B-21 and does not impose any requirements on the benzene content of the system.

Recommended use:

UV paper varnish, LED-UV varnish, UV offset/screen-printing inks, UV coatings for plastics and wood products, and more.

Shelf life:

Store at room temperature, sealed and protected from light. Shelf life: 6 months.

Packaging specifications:

200L packaging drum; 25L packaging drum.

Precautions:

None
