Photoinitiator 6976 is mainly used in various cationic UV curing systems, specially in colorless systems.
The triarylsulfonium salt photoinitiator can be conjugated with three aromatic rings due to the sulfur atom, and the positive charge can be dispersed.

After photoexcitation, it can be cracked to produce polymerization active species, and the photoinitiation activity is high. Good absorption at 365nm. The amazing feature is it cures very fast, good surface dry, no yellowing, no migration,no smell and very cost-effective.
