Storage

Photo-initiator 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.

Known Application

1.TPO is a photo-initiator 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 TiO 2 . Such coatings are characterized by particularly low yellowing. IHT-PI TPO can also be used to cure clear coatings and is particularly suitable when low-odor products are desired.
