Sinocure® TPO Usage

1. Photoinitiators, mainly used for screen printing inks, lithographic printing inks, flexo printing inks, wood coatings, Ink additives.

2. Sinocure® TPO is a highly efficient free radical (I) type, highly efficient photoinitiator. Because of its wide absorption range, its effective absorption peak is 350-400nm, and it absorbs to about 420nm. Its absorption peak is longer than that of conventional initiators, and two free radicals, benzoyl and phosphoryl, can be generated after exposure to light. Both can initiate polymerization, so the photocuring speed is fast. It also has photobleaching effect. It is suitable for thick film deep curing and the coating does not turn yellow. It has low volatility and is suitable for water-based system.

3. This product can replace Photoinitiator TPO;2,4,6-Trimethylbenzoyl diphenylphosphine oxide;Darocure TPO;Lucirin TPO;Photocure TPO;Genocure TPO;Irgacure TPO.
