Ko te UV absorber UV-928 he benzotriazole UV absorber, he kaha ki te whakauru i te rama ultraviolet 270-380 nm, me te tere o te whakauru o te 303 nm me te 345 nm. Kei a ia nga ahuatanga o te pai o te hototahi, te iti o te ngawari, te pai o te marara, te iti o te nekeneke, te pai o te waiariki me te pai o te whakauru, he pai hoki mo te punaha whakamaarama teitei, te paninga paura me te paninga rino hurihuri. Whakakotahitia me te UV292 me te UV123 te whakapumau marama, ka tino whakapai ake i te mauroa o te paninga, me te aukati i te ngaro o te marama paninga, te paheketanga, te kapiti, me te delamination.
Te nuinga whakamahia i roto i: paninga automotive, paninga coil, paninga paura.
