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).

Photoinitiators are widely applied to the UV surface curing system with high photocuring speed and anti-yellowing, such as UV curing coatings, UV photocopying varnish, UV plastic coatings, UV wood coatings, UV glue, silk screen printing inks, lithographic printing inks, flexo printing inks, UV curing adhesives, optical fiber coatings and electronic products, generally used with other photoinitiators. It also can be used together with ultraviolet absorbent when necessary to prevent product aging.
Advantages:
1. Fast photocuring speed
2. Have light-decolourizatio
3. Can be used for thick coating curing
4. Belongs to low-volatility, mild-smell and environment friendly product
5. Anti-yellowing
