In the competitive landscape of coatings manufacturing, delivering products that offer exceptional durability, aesthetic stability, and protection against environmental degradation is crucial. Ultraviolet (UV) radiation from sunlight is a primary culprit behind coating failure, leading to chalking, delamination, color fade, and loss of gloss. For coating formulators and procurement specialists, selecting the right UV absorber is a critical decision. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical manufacturer and supplier from China, offers a premier solution: 2-(2'-Hydroxy-4'-benzoyloxyphenyl)-5-chlorobenzotriazole (CAS 169198-72-5), widely known as UV-366, a highly effective UV absorber tailored for demanding coating applications.

UV-366 is a high-performance benzotriazole UV absorber designed to provide robust protection for a variety of coating systems. Its molecular structure allows it to efficiently absorb UV light, preventing it from initiating degradation processes in the coating binder and pigments. Compared to conventional UV absorbers, UV-366 offers several key advantages that make it ideal for high-performance applications. Its high molecular weight ensures it remains within the coating film, resisting migration and leaching, while its non-volatility and excellent resistance to extraction make it suitable for coatings that undergo high-bake cycles or are exposed to harsh environmental conditions. When you decide to buy this advanced chemical from a reputable China supplier, you are ensuring the longevity and performance of your coatings.

The efficacy of UV-366 in coatings is further amplified by its superior UV absorption efficiency. Its high molar extinction coefficient means it can provide excellent protection at relatively low addition levels, contributing to formulation cost-effectiveness without compromising performance. Furthermore, its light yellow powder form is advantageous as it does not cause unwanted color shifts or yellowing in clear coats or pigmented systems, preserving the intended aesthetic of the final product. For coating chemists and R&D teams, sourcing high-quality UV-366 from a trusted manufacturer in China guarantees a reliable component for formulating premium coatings.

The applications for UV-366 in the coatings industry are diverse and impactful. It is particularly well-suited for automotive coatings, industrial coatings, architectural finishes, and protective coatings where long-term weatherability and color retention are paramount. Its compatibility with various resin systems, including acrylics, polyurethanes, and polyesters, makes it a versatile additive. By choosing to buy UV-366, coating manufacturers can develop products that maintain their appearance and protective functions for extended periods, even under intense sunlight. This translates to enhanced product value and customer satisfaction.
