| Use Pattern |
| TPO-L is a liquid photo-initiator with excellent compatibility, it is especially easy to incorporate into all formulations. |
| Photo-initiator TPO-L absorbs in long wave region of UV spectrum, it can completely cure paints and surfaces pigmented with TiO 2 . |
| It is particularly suited to use in pigmented coatings, white paints and thick film layers requiring low yellowing and low odor. |
| Photo-initiator TPO-L is usually combined with other photo-initiators, like Photo-initiator TPO-L 184, Photo-initiator TPO-L 1173 or BP-Flakes to improve surface cure. |
