AppliedProduct Overview
PowerCure™ PAG209 is a cationic photoinitiator based on diphenyl(4-phenylthio)phenylsulfonium hexafluoroantimonate. The TDS describes strong absorption at 365 nm and its use in cationic UV-curable formulations, particularly light-colored systems. This profile covers the powder form.
Key Features
- Designed for cationic UV-curing systems.
- Strong absorption at 365 nm, as described in the TDS.
- Fast curing and surface-dry performance.
- Low-odor characteristics and suitability for light-colored formulations.

Selected values from the original TDS. Refer to that document for conditions and whether values are typical or specification limits.
Typical Applications
- Cationic UV-curable formulations.
- Light-colored cationic curing systems.
Technical Considerations
The TDS gives a use level of 0.5–3.0 wt% based on total formulation weight. Performance should be verified in the intended formulation.
The document also mentions a 50% solution in propylene carbonate as an alternative supply form. That solution is distinct from the powder described here. Consult the SDS for handling and safety information.
