The performance and longevity of coatings are often dictated by their ability to withstand environmental stressors, with ultraviolet (UV) radiation being a primary culprit for degradation. For manufacturers of paints, varnishes, and protective finishes, incorporating effective UV absorbers is not just an option, but a necessity. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical supplier, emphasizes the crucial role of UV Absorber UV-P (CAS 2440-22-4) in enhancing the durability and aesthetic appeal of coatings.

UV Absorber UV-P, scientifically known as 2-(2H-benzotriazol-2-yl)-p-cresol, belongs to the hydroxyphenyl benzotriazole class of chemicals. Its core function is to absorb UV light within a specific spectrum (270-380nm) and dissipate the energy as heat, thereby preventing the UV radiation from initiating chain reactions that degrade the polymer binders and pigments within a coating formulation. This inherent property makes UV-P an invaluable additive for applications exposed to sunlight, such as architectural coatings, automotive finishes, and industrial protective layers.

The effectiveness of UV-P in coatings is further amplified by its high purity (≥99%) and excellent compatibility with a wide range of resin systems. Whether formulating for acrylics, polyurethanes, polyesters, or epoxies, UV-P integrates seamlessly, providing robust protection against yellowing, chalking, gloss reduction, and loss of mechanical properties. For formulators and procurement professionals, purchasing UV-P from a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures access to a consistent, high-quality product. Our competitive pricing and stable supply from China make us an ideal partner for your coating formulation needs.

Beyond UV absorption, UV-P often works synergistically with Hindered Amine Light Stabilizers (HALS) to provide a comprehensive protection package. While UV absorbers act as sacrificial shields, HALS scavenge free radicals that may form during the degradation process. This combined approach significantly extends the lifespan and maintains the aesthetic integrity of the coated surface. When you buy UV-P, consider its potential as part of a dual-protection system to achieve superior long-term performance.

The typical usage levels for UV-P in coatings are generally low, usually ranging from 0.1% to 1.0% by weight, depending on the coating's intended application, film thickness, and expected UV exposure. Its low toxicity and ease of handling further contribute to its appeal among coating manufacturers. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supporting the coatings industry by providing essential raw materials like UV-P, ensuring that your products deliver on their promise of protection and durability.
