中固化学®CAT-263 is a triarylsulfonium salt photoinitiator. Since the sulfur atom can be conjugated with three aromatic rings, the positive charge is dispersed, and it can be cleaved after light excitation to produce polymerization active species with high initiation activity. It has good absorption at 365nm and has the characteristics of fast curing speed, good surface drying, no yellowing, no migration, and no odor.
