In the field of material science and chemical manufacturing, understanding the specific properties of additives is key to optimizing product performance. 2-(2H-Benzothiazol-2-yl)-6-(dodecyl)-4-methylphenol, commercially known as UV-571, is a sophisticated liquid UV absorber that offers a compelling combination of chemical stability, effective UV protection, and processability.

NINGBO INNO PHARMCHEM CO.,LTD. provides UV-571, a liquid benzotriazole UV absorber designed for high-performance applications. Its chemical structure is carefully engineered to provide efficient absorption of ultraviolet radiation, acting as a shield to protect sensitive materials from photodegradation. The molecular formula C25H35N3O and a molecular weight of approximately 393.57 g/mol are key identifiers of its composition.

One of the most significant technical advantages of UV-571 is its liquid form, which simplifies handling and incorporation into various formulations. Unlike many solid UV absorbers, UV-571 exhibits excellent solubility in a wide array of common organic solvents and monomers. This characteristic is particularly beneficial for manufacturers who can integrate it directly into polymerization processes or easily blend it into liquid formulations, such as coatings, adhesives, and personal care products. The technical data highlights its solubility in solvents like toluene, methylene chloride, and n-hexane, while its insolubility in water ensures it remains in hydrophobic matrices.

Furthermore, UV-571 is characterized by its low volatility. This property is crucial for applications involving high processing temperatures. It ensures that the UV absorber remains in the material, providing long-lasting protection without significant loss through evaporation. This low volatility contributes to the overall durability and sustained performance of the end product, a critical aspect of durable plastic formulations and protective coatings.

The efficiency of UV-571 is further demonstrated by its minimal impact on the color of the substrate. It provides excellent light stability and protection efficiency without imparting yellowness, making it suitable for applications where color fidelity is essential, such as in clear plastics, transparent coatings, or light-colored materials. Its specified light transmittance values at different wavelengths (e.g., ≥ 95% at 460 nm) confirm its clear and effective absorption profile.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying high-purity chemical auxiliaries that meet rigorous industry standards. UV-571’s specifications, including its high assay content (≥99%), low volatile matter (≤0.50% max), and minimal ash content (≤0.1% max), underscore its quality and reliability. By providing detailed technical information and high-quality products, NINGBO INNO PHARMCHEM CO.,LTD. empowers manufacturers to achieve superior material performance and longevity through effective UV protection strategies.
