TPO-L is a free radical photoinitiator with long absorption wavelengths (273 nm and 370 nm) and excellent deep-curing performance. It exhibits good photo-bleaching properties and low odor, making it particularly suitable for LED-curable coatings and inks. It can be used alone or with 184 to achieve a more balanced curing performance.
