Cationic Curing Clear Coat Photoinitiator
This product is triarylsulfonium hexafluoroantimonate. Because the sulfur atom can be conjugated with three aromatic ring parts, the positive charge is dispersed, and can be cleaved after light excitation to produce polymerization active species, which has stronger reactivity than phosphate.
The addition amount is only 40-60% of triarylsulfonium hexafluorophosphate, which has the characteristics of higher cross-linking hardness, no migration, odorless, temperature resistance, and good deep curing. The absorption wavelength is 290nm, which combines high performance and economy. Used in cationic curing transparent coatings, adhesives, LED packaging, inks and other fields.
