Applications

TPO-L  is a liquid photoinitiator for resins containing acrylic groups and for  unsaturated polyesters containing styrene. As a liquid photoinitiator with excellent compatibility, it is especially  easy to incorporate into all formulations. Since TPO-L absorbs in long wave region of UV spectrum, it can completely cure  paints and surfaces pigmented with TiO₂. It is particularly suited  to use in pigmented coatings, white paints and thick film layers requiring  low yellowing and low odor.

Storage  Conditions

TPO-L is sensitive to visible light and any exposure to sunlight  should be avoided. Kept at ambient temperature (25-40℃) 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.
