San-Apro’s CPI™ line of Photoacid Generators (PAGs) are unique, high purity photoinitiators for UV-curing of cationic raw materials. These include the 200-series products that match curing performance of hexafluoroantimonate (SbF6)-based sulfonium salts but without the presence of the heavy metal Antimony (Sb).
Product examples include:
- CPI-100P (PF6-based Sulfonium Salt in 50% Propylene Carbonate)
- CPI-101A (SbF6-based Sulfonium Salt in 50% Propylene Carbonate)
- CPI-200K (Novel FluoroPhosphate Anion-based Sulfonium Salt in 50% Propylene Carbonate)
- CPI-210S (100% Powder form of CPI-200K)
