SINOCURE® CAT-935 is a cationic 光引发剂 belonging to the iodonium salt family. It is designed for use in cationic UV-curing systems, especially in light-colored formulations. The product exhibits high photoinitiation activity, 快速固化 speed, excellent surface cure, non-yellowing, non-migration, and odorless characteristics. When used with appropriate sensitizers, it shows good absorption at 365 nm and 385 nm, making it highly effective for LED-curing applications. It offers excellent cost-performance with low dosage requirements.
