The advancement of UV-curing technology has revolutionized industries ranging from printing and packaging to automotive coatings and electronics. At the heart of this technology are photoinitiators, the critical compounds that absorb UV light and trigger the polymerization process. Among these, 4-Chlorobenzophenone (CAS 134-85-0) has established itself as a highly effective and reliable Type II free radical photoinitiator. For formulators and procurement specialists in the B2B chemical market, understanding its properties and benefits is essential for optimizing UV curing applications.

As a leading manufacturer and supplier, we understand the nuanced requirements of UV-curable systems. 4-Chlorobenzophenone is celebrated for its excellent performance characteristics. Its mechanism as a Type II photoinitiator involves the absorption of UV radiation and subsequent hydrogen abstraction from a co-initiator (often a tertiary amine). This process generates free radicals that initiate the rapid polymerization of monomers and oligomers, leading to a cured film. The efficiency of this process is directly linked to the photoinitiator's absorption spectrum and its ability to interact effectively with the UV light source.

A significant advantage of 4-Chlorobenzophenone is its low volatility and mild odor, contributing to a safer and more pleasant working environment. Furthermore, its strong anti-yellowing capability is a prized attribute, especially in applications demanding high clarity and color stability, such as clear overprint varnishes, white inks, and protective coatings. This ensures that the cured material retains its original appearance over time, resisting the degradation that can occur with less stable photoinitiators.

Procurement managers and R&D scientists often look for suppliers who can guarantee consistent quality and supply reliability. We pride ourselves on being a trusted manufacturer of 4-Chlorobenzophenone, offering a product with a typical purity of ≥99%. This high purity ensures predictable performance and minimizes the risk of unwanted side reactions or defects in the final cured product. Proper storage in cool, dry, and well-ventilated conditions, while keeping containers sealed, is recommended to maintain its integrity.

For those looking to buy 4-Chlorobenzophenone to enhance their UV curing formulations, consider the benefits of partnering with a knowledgeable supplier. We provide competitive pricing for bulk orders and can supply detailed technical specifications, including CAS number, molecular formula, and safety data sheets. Whether you are formulating for printing inks, plastic coatings, or adhesives, our 4-Chlorobenzophenone is an ideal choice for achieving superior curing performance, durability, and aesthetic quality.
