Light yellow powder photoinitiator is used for curing, with good surface curing and deep curing. Yellow to yellow-green crystalline particles, UV curable coatings and inks.

Benzophenone is a ketone compound containing two phenyl groups and has high UV absorption ability. The light absorption ability of benzophenone is mainly determined by the ketone group in its molecule. The carbon-based carbon atoms in the ketone group absorb UV light and cause the electrons in the molecule to jump to an excited state. Molecules in this excited state have higher energy and can initiate photochemical reactions.

Benzophenone and its derivatives are closely related to our lives. In personal care, they are used in many products such as nail polish, sunscreen, lip balm, etc.
