CPI-310FG
i-line Highly sensitive sulfonium salt type photoacid generator. Although it is a non-Sb type because it uses special anion, it has the same acid strength as the SbF6 anion product and exhibits high cationically polymerizable properties. In addition, the cured product is excellent in low metal corrosiveness.

Q&A
- What is the absorption wavelength?
-
The i-line (365 nm) absorbs about 600 [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).
- What are the characteristics of FG (special anion)?
-
It has high acid strength and reactivity equivalent to HSbF6. In addition, corrosion of peripheral members and coloring during heat curing can be suppressed.
- Are there types with different generated acids?
- There is CPI-310B, which is a B(C6F5)4 anion.We have a track record of developing other anions such as sulfonates, so if you have any anions that you are interested in, please feel free to contact us.
- How much should I add?
-
Add about 0.5 to 2 wt% to the resin, depending on the application and film thickness.
- What film thickness is suitable?
-
A medium film thickness of about 50 μm is suitable, although it depends on the application and the amount of addition.For thin films of 10 μm or less, the type with a large molar extinction coefficient (CPI-400 series, etc.) is suitable because the effect of transmittance is small.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.
