IK-1Ionic Photoacid Generator, Photo-Cationic Polymerization Initiator, Iodonium

Characteristics and Applications

IK-1 is a special grade iodonium salt type photoacid generator only available from us. Combined with a sensitizer, it can handle longer wavelengths. The anionic structure is a special phosphorus system of our own design, which exhibits high cationic polymerization. It also has excellent solubility in various solvents and monomers, including non-polar organic solvents. It can also be used as a high-temperature type thermal acid generator. IK-1 is a non-solvent type powder product.

Differences from sulfonium salt types

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.
Absorption Wavelengths without a Sensitizer

According to the result in acetonitrile solution, there is an absorption wavelength up to about 300 nm.
Polymerization initiation temperature

When blended with bisphenol A glycidyl ether, polymerization starts at 210°C.
Characteristics of PF3(C2F5)3 anion

Although non-Sb-based, it has acid strength equivalent to HSbF6 and exhibits high cationic polymerization. Acid generators with this anion also have excellent solubility in a variety of solvents and monomers, including non-polar organic solvents.
Regarding different types of acids generated

We have an FG anion, IK-1FG.
We have experience in the development of other anions as well, so please feel free to contact us if you are interested in any anions.
Recommended amount of additive

Add about 0.5 to 1 wt% to the resin, depending on the application and film thickness.
