4-methylbenzophenone

4-Methylbenzophenone (CAS 134-84-9) is a photoinitiator and UV-reactive intermediate for polymer processing, coatings and printing.

Where is 4-methylbenzophenone used?

• UV-curable coatings and inks: photoinitiator triggering polymer cross-linking on UV exposure
• Printing and packaging: energy-curable ink formulations for fast cure speeds
• Adhesives and sealants: photoinitiated bonding for heat-sensitive substrates
• Polymer stabilizer blends: UV-stabilizing component protecting plastics from photodegradation
• It absorbs UV radiation to initiate photochemical reactions, enabling rapid curing and cross-linking.

Good to know: Formulations meet low migration potential requirements, a critical process standard for industrial printing.

Commercial specifications

• Purity typically 99% or above for photoinitiator-grade applications
• Packaging from kilogram quantities to bulk drums
