Synonym:UV Cationic Photoinitiator 6993;UVI-6993;UVI-6976;
Mixed Sulfonium Hexafluoroantimonates & propylene carbonate
CAS NO:71449-78-0 & 89452-37-9 & 108-32-7
Molecular Formula: C24H19S2.SbF6 & C36H28S3.Sb2F12 & C4H6O3
Molecular Structure:
&
General Information:
The triarylsulfonium salt photoinitiator has high photoinitiation activity because the sulfur atom can be partially conjugated with three aromatic rings, and the positive charge is dispersed. After light excitation, it can undergo cleavage to produce polymerization active species; it has good absorption at 365nm; It has the characteristics of fast curing speed, good surface drying, no yellowing, no migration, and no smell.
