IK-1FG
Iodonium salt type photoacid generator.
By using a sensitizer, it is possible to handle long wavelengths. Since it uses a special anion, it has the same acid strength as the HSbF6 anion product even though it is non-Sb-based, and exhibits high cationically polymerizable properties. In addition, the cured product is excellent in low corrosiveness and low colorability when heated at high temperature.
It can also be used as a high temperature type thermal acid generator.

Q&A
- What is the difference between the iodonium salt type photoacid generator and the sulfonium salt type?
-
The iodonium salt type has relatively poor storage stability when compounded with a cationically polymerizable resin compared to the sulfonium salt type, but a large sensitizer effect can be expected when used in combination with a sensitizer.
- What is the absorption wavelength without the sensitizer?
-
According to the result in acetonitrile solution, there is an absorption wavelength up to about 300 nm.
- What should I use as a sensitizer?
-
Anthracene-based sensitizers such as dibutoxyanthracene (DBA) and thioxanthone-based sensitizers such as isopropylthioxanthone (IPTX) can be expected to have a large sensitizing effect.
- What is the polymerization start temperature as TAG?
- When blended with bisphenol A type glycidyl ether, polymerization starts at 210 °C.
- 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 IK-1 which is a PF3(C2F5)3 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.
- How much should I add?
-
Add about 0.5 to 1 wt% to the resin, depending on the application and film thickness.
