In the dynamic world of industrial coatings and printing, UV curing technology has revolutionized production processes by offering rapid drying times, enhanced durability, and reduced environmental impact. At the heart of this technology lies the photoinitiator, a critical component that absorbs UV light and initiates the polymerization process. Among the most effective and widely used photoinitiators is 4-Chlorobenzophenone (CAS: 134-85-0).

Understanding 4-Chlorobenzophenone as a Photoinitiator

4-Chlorobenzophenone, also known as Photoinitiator CBP, is a Type II free-radical photoinitiator. Its efficacy stems from its ability to absorb UV radiation within specific wavelengths, typically around 204nm and 258nm, and then transfer this energy to a co-initiator, usually a tertiary amine. This energy transfer process generates free radicals, which then initiate the chain polymerization of monomers and oligomers in UV-curable formulations. The result is a rapid and efficient curing process, transforming liquid coatings or inks into solid, durable films.

Advantages in UV-Curable Systems

As a leading supplier of chemical intermediates, we understand the importance of performance and reliability. 4-Chlorobenzophenone offers several key advantages for manufacturers in the UV curing industry:

  • Fast Curing Speed: Its photochemical properties contribute to significantly reduced curing times, boosting production throughput.
  • Low Odor and Minimal Yellowing: Compared to some older photoinitiators, 4-Chlorobenzophenone exhibits low volatility and a milder odor, alongside good anti-yellowing properties, making it ideal for high-quality finishes and applications sensitive to discoloration.
  • Versatility: It is highly effective in a wide range of UV-curable systems, including clear lacquers, plastic coatings, wood coatings, adhesives, offset printing inks, screen printing inks, and flexo inks.
