Benzophenone is widely employed as a photo initiator in UV-curing applications such as inks, imaging and clear coatings in the printing industry. It acts as a UV blocker to prevent photo-degradation of the packaging polymers or its contents. It protects some products such as perfumes and soaps from ultraviolet light. It serves to manufacturers to package the product in clear glass or plastic.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
La benzofenona es ampliamente empleada como iniciador fotográfico en aplicaciones de curado por UV como tintas, imágenes y recubrimientos transparentes en la industria de la impresión. Actúa como un bloqueador UV para evitar la fotodegradación de los polímeros de embalaje o de su contenido. Protege algunos productos como perfumes y jabones de la luz ultravioleta. Sirve a los fabricantes para envasar el producto en vidrio transparente o plástico.
