TPO-L is a highly efficient Free Radical Type I liquid photoinitiator which is used to initiate UV polymerization of resins containing acrylic groups and of unsaturated polyesters containing styrene.

Applications:
− Screen Inks − Offset Inks
− Flexo Inks − Photoresists
− Overprint Varnishes − Printing Plates

Features/Benefits:
As a liquid photoinitiator with excellent compatibility, it is especially easy to incorporate into all formulations. Since TPO-L absorbs in the long wave region of UV spectrum, it can completely cure paints and surfaces pigmented with TiO2.
