Photoinitiator TPO is used for curing styrene-based unsaturated polyesters and acrylic resins. Its absorption in the long-wave region of the UV spectrum can fully cure even white paints and surfaces pigmented with TiO2. Such coatings are characterized by particularly low yellowing. It can also be used to cure clear coatings and is particularly suitable for low-smell application.
