Product Description
TPO is an efficient free radical (I) type photoinitiator that absorbs in the long wavelength range, which has the advantages of fast light curing speed, yellowing resistance, low post-polymerization effect, no residue, low volatility, low odor, etc. It also has photobleaching effect, excellent thermal stability, no chemical reaction occurs when heated to 180°C, and good storage stability.
It is suitable for deep curing of thick films, especially for white UV curing coatings, UV curing adhesives
, UV optical fiber coating and printing inks, and is widely used.
The recommended addition amount is 0.5-3.0wt% (colored system) and 0.3-2.0wt% (transparent system).
