Ingredients	819	Purity:	≥99%
Molecular formula:	C26H27O3P	Volatile matter:	≤0.5%
Appearance:	yellow powder	Ash	≤0.1%
Melting point:	127 - 133 ºC	Absorption peak	295,370nm

Description

The effective absorption peak of Bapo is between 350 ~ 400 nm, and the absorption peak is about 390 nm. The absorption peak

is longer than that of the conventional initiator. Two free radicals, benzoyl and phosphatidyl, were formed after irradiation, which

initiated the photopolymerization reaction. Therefore, Bapo has the advantages of fast curing speed and good 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. The absorption peak is longer than that of the conventional initiator. Two free radicals, benzoyl and phosphatidyl, were

photolithography resin, composite coatings and other photoinitiator 819 also has a certain response to near-infrared (Nir) light, the

absorption wavelength of 819 is about 780-820NM, so 819 has a wide application in the field of biomedicine for its near infrared (NIR) .
