CPI-200K/CPI-210SIonic Photoacid Generator, Photo-Cationic Polymerization Initiator (Sulfonium)

Characteristics and Applications

CPI-200K/210S is a special grade sulfonium salt type photoacid generator only available from us.
Using a proprietary process, the cation is a high-purity monomer, which provides excellent storage stability when blended with cationic polymerizable monomers.
The anionic structure is a special phosphorus system of our own design.
Although it is antimony-free, it has the same acid strength as antimony products (e.g., CPI-101A) and exhibits high cationic polymerization. It also has excellent solubility in a variety of solvents and monomers, including non-polar organic solvents.
CPI-200K is a 50% propylene carbonate solution product, and CPI-210S is a solvent-free powder product.

CPI-200K/CPI-210S 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).
  • 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 are CPI-100P, which is a PF6 anion, and CPI-101A, which is an SbF6 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 0.5 to 1 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, 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.
