TPO 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. Such coatings are characterized by particularly low yellowing. TPO can also be used to cure clear coatings and is particularly suitable when low-odor products are desired.
Storage Conditions
TPO is sensitive to visible light and any exposure to sunlight should be avoided. Kept at low/ambient temperature and dry conditions. Avoid contacting with strong oxidants.
The product is stable for 2 years if stored in original, sealed containers under above-mentioned conditions.
