Application

Benzophenone serves multiple essential functions across various industries due to its unique properties as a free radical photoinitiator and UV absorber. Primarily, it is utilized in free radical UV curing systems, significantly benefiting the production of coatings, inks, and adhesives. Additionally, benzophenone is an important synthetic intermediate in the manufacturing of pharmaceuticals and agricultural chemicals. Its aromatic characteristic and UV-absorbing capacities make it a valuable component in the perfume and cosmetic industries, where it not only adds a flowery note to fragrances but also enhances the effectiveness of sunscreens, hair conditioners, lotions, and lipsticks. The versatility of benzophenone extends to its use in plastics, lacquers, and coatings, ensuring durability and protection through UV absorption.
