In the realm of advanced material science and manufacturing, ultraviolet (UV) curing technology has become indispensable. This rapid and efficient process relies heavily on specialized chemicals known as photoinitiators. Among these, Benzophenone (CAS 119-61-9) stands out as a cornerstone, particularly as a Type II photoinitiator. Understanding its properties and application is crucial for professionals in the ink, coating, and adhesive industries. As a prominent manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-quality Benzophenone to meet these demanding needs.

Benzophenone, also chemically known as Diphenylmethanone or Diphenyl Ketone, is an organic compound with the molecular formula C13H10O. It typically presents as white crystal flakes and is recognized for its high purity, often exceeding 99%. Its primary function in UV curing is to initiate polymerization reactions when exposed to UV light. Unlike Type I photoinitiators, Type II photoinitiators like Benzophenone require a co-initiator, often an amine synergist. Upon UV absorption, Benzophenone undergoes excitation and then abstracts a hydrogen atom from the co-initiator. This process generates the free radicals necessary to kickstart the polymerization of monomers and oligomers, leading to a rapidly cured, solid material.

The versatility of Benzophenone makes it a sought-after ingredient in various sectors. In the ink and coating industries, it's vital for achieving fast cure speeds, excellent adhesion, and desirable finish properties. Its use extends to cosmetic formulations, where it functions as a UV absorber, protecting both the product and the end-user from harmful UV radiation. Furthermore, Benzophenone serves as a valuable intermediate in the synthesis of pharmaceuticals and pesticides, highlighting its broad chemical utility. When considering purchasing Benzophenone, sourcing from a reliable manufacturer in China, such as NINGBO INNO PHARMCHEM CO.,LTD., ensures quality and competitive pricing.

For businesses looking to optimize their UV curing processes, understanding the solubility and compatibility of Benzophenone is key. While it exhibits weak polarity and is not readily soluble in water, it shows good solubility in many organic solvents and alcohols, especially at elevated temperatures. This characteristic is important for formulators to consider when designing ink or coating systems. The ability to buy Benzophenone with consistent quality is paramount for product performance.
