  • Applications

    Chimassorb 944, CAS 71878-19-8, is a HALS (hindered amine light stabilizer) used to improve weathering resistance and oxidative stability of polymer resins and coatings. Typical applications include its use as an additive in polymer matrices (such as polypropylene, polyethylene, PVC, and PET) to extend outdoor life; in coatings and paints for architectural, automotive, and wood-related applications to reduce UV-induced degradation; in packaging films and related plastics to protect mechanical properties under light exposure; in adhesives and sealants to maintain performance under UV/oxidative conditions; and in certain inks and other plastic-based formulations requiring light stability.
