Coatings and paints play a vital role in protecting substrates and providing aesthetic appeal. However, exposure to sunlight, particularly its ultraviolet (UV) component, can lead to significant degradation, resulting in gloss loss, chalking, color fading, and delamination. To combat these detrimental effects, the incorporation of UV absorbers into coating formulations is essential. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier, offers UV Absorber 326, a highly effective solution designed to enhance the durability and appearance of various coatings.

UV Absorber 326, identified by its CAS number 3896-11-5, is a benzotriazole-based UV absorber that excels at absorbing UV radiation in the critical 300-400 nm wavelength range. This absorption mechanism prevents UV photons from initiating photo-oxidative degradation of the coating's polymer binders, pigments, and other additives. By dissipating the absorbed energy as heat, UV Absorber 326 effectively shields the coating, preserving its integrity and appearance over time. Its minimal absorption in the visible spectrum ensures that it does not compromise the color of the coating, a crucial factor for many paint and coating applications.

The benefits of using UV Absorber 326 in coatings are manifold. It provides excellent lightfastness, meaning it helps maintain the original color and gloss of the paint film even under prolonged UV exposure. Its low volatility and good thermal stability make it suitable for a wide range of coating applications, including those that involve moderate to high curing temperatures. Furthermore, its compatibility with various resin systems, such as acrylics, polyurethanes, and polyesters, makes it a versatile additive for formulators.

For coating manufacturers seeking to buy UV Absorber 326, understanding its role in the formulation is key. It is often used at concentrations ranging from 0.2% to 1.0% by weight, depending on the specific resin, pigment concentration, and the expected service environment. For enhanced protection against harsh weather conditions, UV Absorber 326 can be synergistically combined with Hindered Amine Light Stabilizers (HALS), which scavenge free radicals generated during the degradation process. This combined approach provides superior long-term stability and performance for exterior coatings.
