Molecular Formula: C14H16O2
Molecular Structure:
SINOCURE® PSS-DBA is a high-performance photo-sensitizer designed to enhance the efficiency of UV curing processes. It enables effective sensitization of both radical photo-initiators and cationic photo-acid generators (PAGs) under 365–405 nm UV-LED light sources, even with low inherent absorbance in this range. It is particularly suited for applications requiring low yellowness and high transparency.
