Description
Lencolo 5007 Due to its broad absorption range, TPO has an effective absorption peak of 350-400 nm and continues to absorb up to around 420 nm. Its absorption peak is longer than that of conventional initiator. Upon irradiation, it generates both benzoyl and phosphinoyl radicals, each capable of initiating photopolymerization, resulting in fast UV curing. It also exhibits photobleaching properties, making it suitable for thick-film deep curing and non-yellowing coatings. Low volatility makes it suitable for use in water-based systems.
