The industrial application of UV curing technology offers significant advantages, including speed, energy efficiency, and reduced environmental impact. At the heart of this technology lies the photoinitiator, and Benzophenone (CAS 119-61-9) remains a workhorse in many formulations. As a prominent manufacturer and supplier of this essential organic intermediate, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supporting industries that rely on its performance.

Benzophenone, chemically known as Diphenylmethanone or Diphenyl Ketone, is classified as a Type II photoinitiator. Its function is to absorb UV radiation and then, in conjunction with a synergist (often an amine), generate the free radicals required to initiate the rapid polymerization of monomers and oligomers. This process is fundamental to curing inks, coatings, adhesives, and composites used across a vast array of industrial applications, from printing and packaging to automotive finishes and electronics. The high purity (≥99%) of Benzophenone ensures consistent and predictable curing performance, a critical factor for industrial manufacturing processes.

The mechanism by which Benzophenone operates is crucial for formulators to understand. Upon absorbing UV light, Benzophenone enters an excited triplet state. It then abstracts a hydrogen atom from a readily available donor, such as an amine co-initiator, creating an organic radical. This radical then initiates the chain polymerization of acrylate or methacrylate groups, which are common in UV-curable resins. This controlled initiation process allows for precise curing profiles and material properties.
