Photoinitiator GR-SS056 Applications
-
Cationic UV Curing Systems: Mainly utilized in cationic photocuring formulations, providing high reactivity and efficiency upon light excitation.
-
Light-Colored Formulations: Highly suitable for clear and light-colored UV coatings, inks, and adhesives without causing post-curing discoloration.
-
Non-Yellowing Surface Coatings: Ideal for industrial surface coatings requiring fast curing speed, excellent surface drying, and zero yellowing.
-
Low-Odor & Non-Migration Applications: Used in sensitive printing inks and protective coatings where non-migration, high cost-performance, and odor-free properties are strictly required.
Photoinitiator GR-SS056 Features
Triarylsulfonium salt photoinitiators can be conjugated with three aromatic rings because the sulfur atom can be dispersed, and the positive charge can be dispersed. After light excitation, it can be cracked to produce polymerization active species, and the photoinitiator activity is high; It has good absorption at 365nm; it has the characteristics of fast curing speed, good surface drying, no yellowing, no migration, no odor, etc., and has high cost performance.
