Company info

CPI-100P/110PIonic Photoacid Generator, Photo-Cationic Polymerization Initiator (Sulfonium)

Characteristics and Applications

CPI-100P/110P are our general-purpose grade sulfonium salt type photoacid generators.
CPI-100P/110P are made by a proprietary process that produces a high-purity cationic monomer, which provides excellent storage stability when blended with cationic polymerizable monomers.
The anionic structure is PF6, which has cationic polymerization performance, and the cured product has excellent low coloration when heated at high temperatures.
CPI-100P is a 50% propylene carbonate solution product, and CPI-110P is a solvent-free powder product.

CPI-100P/110P Structure
  • Regarding absorbed wavelengths
    The i-line (365 nm) absorbs about 80 [M-1 cm-1] in terms of molar extinction coefficient. There is no absorption in the h-line (405 nm) and g-line (436 nm).
  • Regarding different types of acids generated
    There are CPI-101A, which is a SbF6 anion, and CPI-210S, which is a PF3(C2F5)3 anion.
    We also have a track record of developing sulfonates such as trifluoromethanesulfonic acid.
    If you have any other anions that you are interested in, please feel free to contact us.
  • Recommended amount of additive
    Add about 5 wt% to the resin, depending on the application and film thickness. In the case of cationic polymerization reaction, the amount of addition can be reduced by using the generated acid type (CPI-101A, 210S) with high acid strength.
  • Recommended film thickness
    Although it depends on the application and the amount of addition, the molar extinction coefficient is small, so even a thick film of 100 μm or more has high light transmittance in the depth direction and can generate acid to the deep part. On the other hand, in the case of a thin film of about 10 μm, the type with a large molar extinction coefficient (CPI-400 series, etc.) is suitable because the effect of transmittance is small. The CPI-300 series is suitable for medium film thicknesses of about 50 μm.
  • Recommended sensitizers
    It has a high sensitizing effect for anthracenes such as dibutoxyanthracene (DBA).
    On the other hand, the sensitizing effect of thioxanthone such as isopropyl thioxanthone (IPTX) is low.
