Description
Because of its wide absorption range, TPO has an effective absorption peak of 350-400 nm and has been absorbed to about 420 nm. Its absorption peak is longer than that of conventional initiator. After irradiation, two free radicals, benzoyl and phosphatidyl, can be formed, which can initiate photopolymerization. Therefore, the photocuring speed of TPO is fast, and it also has photobleaching effect. It has low volatility and is suitable for water-based applications.
