  • Applications

    Sodium Benzotriazolyl Butylphenol Sulfonate is a water-dispersible benzotriazole UV absorber that protects materials from UV/light-induced degradation. It functions as a stabilizer in aqueous formulations and in polymer systems, helping to maintain color and mechanical properties under sun exposure. Common applications include UV stabilization of polymers and plastics (such as PVC and polyolefins), protection of coatings and paints (architectural and industrial coatings), formulation of inks and printing systems, and use in adhesive/sealant formulations. It may also be employed in packaging materials and films where water dispersibility and low VOC content are advantageous.
