SINOCURE® PSS-DAA Et is a 耐黄变, long‑wavelength cationic 光增感剂 specifically developed for UV-LED 固化 systems. It efficiently sensitizes cationic photoinitiators, enabling high 固化 speed while significantly reducing yellowing of the 固化薄膜. It is particularly 适用于 for transparent or light‑colored UV curable systems where optical performance and yellowing resistance are critical.
