Ntchito:UV-5411 ndi chida chapadera chokhazikitsa zithunzi chomwe chimagwira ntchito bwino m'njira zosiyanasiyana za polymeric: makamaka mu ma polyester, ma polyvinyl chloride, ma styrenics, ma acrylic, ma polycarbonate, ndi ma polyvinyl butyal. UV-5411 imadziwika kwambiri chifukwa cha kuyamwa kwa UV kwamitundu yosiyanasiyana, mtundu wake wochepa, kusasinthasintha pang'ono, komanso kusungunuka bwino kwambiri. Ntchito zambiri zomwe zimagwiritsidwa ntchito zimaphatikizapo kupanga, mapepala, ndi zinthu zowunikira pazenera, zizindikiro, zapamadzi ndi zamagalimoto. Ntchito zapadera za UV-5411 zimaphatikizapo zokutira (makamaka ma mosets pomwe kusasinthasintha kochepa kumakhala vuto), zinthu zojambulira zithunzi, zomatira, ndi zinthu zosalala.
