Description

The effective absorption peak of TPO is between 350 ~ 400nm, and The absorption peak is about 420nm. The absorption peak is longer than that of The conventional initiator. Two kinds of free radicals, benzoyl and phosphatidyl, were formed after irradiation, which initiated the photopolymerization reaction. Therefore, TPO has the advantages of fast curing speed and photobleaching effect. It has low volatility, suitable for white system and black system applications. Widely used in UV-curable coatings, inks, UV-curable adhesives, optical fiber coatings, photoresist, photopolymer plates, three-dimensional photolithography resin, composite coatings, and so on
