CPI-410SIonic Photoacid Generator, Photo-Cationic Polymerization Initiator (Sulfonium)

Characteristics and Applications

CPI-410S is a sulfonium salt type photoacid generator with high sensitivity to i- and h-rays, a special grade unique to our company. The anionic structure is a special phosphorus system of our original design, which exhibits high cationic polymerization. It also has excellent solubility in a variety of solvents and monomers, including non-polar organic solvents. CPI-410S is a non-solvent type powder product.

CPI-410S Structure
  • Regarding absorbed wavelengths
    The i-line (365 nm) absorbs about 9600 [M-1 cm-1] in molar extinction coefficient, and the h-line (405 nm) absorbs about 1380 [M-1 cm-1].
    There is almost no absorption in the g-line (436 nm).
  • Characteristics of PF3(C2F5)3 anion
    Although it is a non-Sb type, it has an acid strength equivalent to that of HSbF6 and exhibits high cationically polymerizable properties. In addition, the acid generator with this anion has excellent solubility in various solvents and monomers including non-polar organic solvents
  • Regarding different types of acids generated
    There is CPI-410B, which is a B(C6F5)4 anion.
    We have a track record of developing other anions, so if you have any anions that you are interested in, please feel free to contact us.
  • Recommended amount of additive
    Add about 0.5 to 2 wt% to the resin, depending on the application and film thickness.
  • Recommended film thickness
    Although it depends on the application and the amount of addition, a thin film of 10 μm or less, which is less affected by the transmittance, is suitable.
    In the case of a thick film of 100 μm or more, the type with a small molar extinction coefficient (CPI-100, 200 series, etc.) has high light transmittance in the depth direction and can generate acid to the deep part. The CPI-300 series is suitable for medium film thicknesses of about 50 μm.
