Cationic Catalysts

Polyset is a technological leader in cationic systems. In that effort, Polyset has introduced the PC-2500 series diaryliodonium and triarylsulfonium cationic catalysts. These catalysts exhibit good solubility in a variety of commercially available resins, along with high photoactivity, especially when used in conjunction with applicable photosensitizers. Polyset is developing formulated products based on PC-2500 series cationic catalysts and Polyset’s proprietary novel epoxy resins. These resins and catalysts have a variety of applications, including UV-Curable Printing Inks, Nanoimprint Lithography Solutions and E-Beam Coil Coatings.
