Usage |
Tpo is a highly efficient free radical (i), highly efficient photoinitiator that absorbs in the long wavelength range. It has the advantages of fast photocuring speed, yellowing resistance, low post polymerization effect, no residue, low volatilization and low odor. It has photobleaching effect, excellent thermal stability, no chemical reaction when heated to 180 °c, and good storage stability. It is suitable for thick film deep curing, uv curing coatings, adhesives, optical fibers and inks which are especially suitable for white systems. It is recommended to add 0.5-3.0% by weight (colored system), 0.3-2.0% by weight (transparent system). |
