PAG(I)-2B
| Product name | PAG(I)-2B |
| Chemical name | Bis[4-(tert-butyl)phenyl]iodonium tetrakis(pentafluorophenyl)borate |
| Structural formula | .jpg) |
| Other name | Bis(4-tert-butylphenyl)iodonium tetrakis(pentafluorophenyl)borate |
| CAS NO. | 198641-40-6 |
| Molecular formula | C44H26BF20I |
| Molecular weight | 1072.37 |
| Appearance | Light yellow to white powder |
| Melting point | 145.0-149.0 °C |
| Features and applications | Non-antimony type, yet its acid strength is comparable to that of HSbF6, and it exhibits high cationic polymerizability. It exhibits excellent solubility in various solvents and monomers, including non-polar organic solvents. When used in combination with a sensitizer, it can handle longer wavelengths. It can also be used as a high-temperature thermal acid generator. |
| Recommended dosage of additive | Depending on the application and film thickness, the addition amount is about 0.5–1 wt% of the resin. |
| Recommended sensitizer | Anthracene-based sensitizers, such as dibutoxyanthracene (DBA), and thioxanthone-based sensitizers, such as isopropylthioxanthone (IPTX), are expected to produce significant sensitization. |
| Storage conditions | Store under refrigeration (0–10 °C); store under inert gas; keep away from fire and heat sources; protect from light and moisture (hygroscopic). |
