IK-1

Iodonium salt type photoacid generator.

By using a sensitizer, it is possible to handle long wavelengths. Since it uses a special phosphorus anion, it has the same acid strength as the SbF6 anion product even though it is non-Sb, and exhibits high cationic polymerizable properties. In addition, it has excellent solubility in various solvents and monomers including non-polar organic solvents.

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 the (Rf) nPF6-n 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.
Are there types with different generated acids?
There is IK-1FG which is an FG 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.
