PowerCure™ TPO-L is a photoinitiator for the UV curing of unsaturated polyesters and resins containing acrylic ester groups. Because of its absorption behavior in the long-wave range of the UV spectrum, it is preferably used to cure pigmented UV curable coatings and surfaces as well as UV stabilized coatings.
It is very easily incorporated into coating formulations. It’s good through cure makes it extraordinarily suitable for use in primers and sealers, and its low volatility recommends it for low odor formulations.
PowerCure™ TPO-L is a liquid photoinitiator for pigmented UV curable coatings for UV stabilized topcoats for outdoor use and printing inks, especially opaque white.
