In the dynamic field of UV curing technology, selecting the right photoinitiator is paramount to achieving optimal performance in coatings, inks, and adhesives. Among the widely used compounds, 4-Methylbenzophenone (CAS 134-84-9) stands out as a highly effective Type II photoinitiator, offering distinct advantages for various industrial applications. This article aims to guide procurement managers and R&D scientists in understanding its capabilities and making informed purchasing decisions.

4-Methylbenzophenone, a derivative of benzophenone, is characterized by its molecular structure that efficiently absorbs UV light. This absorption triggers the generation of free radicals, which are essential for initiating the polymerization process of unsaturated monomers and oligomers. Unlike Type I photoinitiators that undergo unimolecular bond cleavage, Type II photoinitiators like 4-Methylbenzophenone require a co-initiator, typically a tertiary amine, to abstract a hydrogen atom and form the initiating radicals. This synergistic action ensures efficient surface cure and depth cure in UV-curable formulations.

The primary applications for 4-Methylbenzophenone as a photoinitiator span across several key industries. In the realm of coatings, it is integral to the formulation of UV-curable clear lacquers, plastic coatings, and wood finishes. Its presence ensures rapid curing upon exposure to UV radiation, leading to durable, scratch-resistant, and aesthetically pleasing surfaces. For printing inks, whether for offset, screen, or flexo printing, 4-Methylbenzophenone plays a crucial role in achieving high-speed printing with excellent adhesion and print clarity.

Beyond its role as a photoinitiator, 4-Methylbenzophenone also serves as an effective UV absorber. This dual functionality makes it a valuable additive in plastics and polymers, shielding them from the damaging effects of ultraviolet radiation. By absorbing UV light, it helps to prevent photodegradation, discoloration, and the loss of mechanical properties over time, thereby extending the lifespan of polymer-based products. This makes it a sought-after chemical intermediate for manufacturers of advanced materials.
