Light acid generator "VC-1 series"

Various combinations with different anions are possible! It has excellent transparency due to its low absorption in the visible light range.

The "VC-1 series" is a light acid generator that achieves both high photodecomposition rates and transparency in the visible light range by introducing a photosensitive area optimized for the cationic component. It has a significant absorption for the i-line (wavelength 365nm), which is the main emission line of high-pressure mercury lamps, while exhibiting low absorption in the visible light range (above 380nm), resulting in excellent transparency. In evaluations of light-curable properties using epoxy resin, it shows curing performance equivalent to the CPI-400 series, indicating a high acid generation rate. Additionally, we offer the "ES-1 series," which demonstrates a higher photodecomposition rate while maintaining similar light absorption characteristics, thanks to further structural optimization of the CPI-400 series. 【Features】 ■ Achieves both high photodecomposition rates and transparency in the visible light range ■ Excellent transparency ■ High acid generation rate ■ Compatible with various anions *For more details, please refer to the PDF document or feel free to contact us.
