High Absorption Cationic Photoinitiator
Because the sulfur atom of the triarylsulfonium salt photoinitiator can be partially conjugated with three aromatic rings, the positive charge is dispersed, and can be cleaved after light excitation to produce polymerization active species. However, the improved absorption efficiency of Uyracure-1600L has been greatly improved. It is not only used in transparent coatings, but can also be cured well in pigmented and filler formulas and even under LED long-wave light sources with suitable resins. It has the characteristics of fast curing speed, good surface drying, no yellowing, no migration, no odor, and temperature resistance. A product that combines high performance with optimal economy. Used in cationic curing transparent coatings, adhesives, LED packaging, inks and other fields.
They are used to prepare photocurable polymers, such as photocurable resins and composites, for a variety of applications including 3D printing, coatings, composite preparation, etc. They are also used in electronics manufacturing to cure packaging of printed circuit boards (PCBs) and other electronic components.
