NPI-601 is a general free radical photoinitiator based on phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide. It offers high curing activity, long absorption wavelengths (377 nm and 405 nm), and excellent deep-curing and photo-bleaching performance. It is particularly suitable for LED-curable coatings and inks, and is often used as a more active complement to TPO.
