Anwendung\uff1a<\/strong><\/p>\n

1. Dieses Produkt ist ein hocheffizienter Ultraviolettabsorber, der ultraviolettes Licht mit einer Wellenl\u00e4nge von 270-340 Nanometern effektiv absorbieren kann.
\n2. Die Lichtstabilisierungsleistung ist \u00e4hnlich wie bei UV-326 und UV-327, aber dieses Produkt hat eine gute Kompatibilit\u00e4t mit Harz, geringe thermische Verfl\u00fcchtigung und hohe Waschbest\u00e4ndigkeit.
\n3. Haupts\u00e4chlich verwendet f\u00fcr Polyolefin (insbesondere Polyethylen), Polyester, Styrolpolymer, Polyamid, Polymethylmethacrylat, Polycarbonat, Elastomer und andere Polymere.<\/p>\n
