Photoinitiator-TPO (CAS: 75980-60-8) is a kind of pale yellow crystal or powder with a chemical formula of C22H21O2P and a molecular weight of 348.37. Stanford Optics offers high-quality Photoinitiator-TPO with competitive pricing.
Photoinitiator-TPO (CAS: 75980-60-8) is a kind of pale yellow crystal or powder, which is used for curing white coatings and thick coatings with titanium dioxide (TiO2) as the pigment. It is a photoinitiator 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.
