    Uses: It is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability 

    for plastics and other organic polymers. UV-P protects polymers as well as organic pigments 

    from UV radiation helping to preserve the original appearance and physical integrity of engi-

    -neered plastics, elastomers, PVC, adhesives, and polyurethanes during outdoor weathering. 

    1. Unsaturated Polyester : 0.2-0.5wt% based on polymer weight

    2. PVC: Rigid PVC : 0.2-0.5wt% based on polymer weight ; Plasticized PVC : 0.1-0.3wt% based 

        on polymer weight

    3. Polyurethane : 0.2-1.0wt% based on polymer weight

    4. Polyamide : 0.2-0.5wt% based on polymer weight
