  • Applications

    Bisdisulizole Disodium, CAS 180898-37-7, is used mainly as a UV absorber and optical stabilizer in polymer systems and coatings. In cosmetics and personal care, it may be used as a UV filter in water-based or oil-based formulations; in polymers/plastics, it helps stabilize plastics against UV-induced degradation; in coatings and inks, it improves colorfastness and light stability; in packaging materials and films, it enhances the film's UV resistance; and in adhesive systems, especially UV-curable formulations, it can be used to maintain bond performance under UV exposure.
