UV-123 ine simba amine light stabilizer, ine yakaderera alkaline, inogona kuderedza kuita neasidhi zvikamu mu coating system, kunyanya yakakodzera muhurongwa hune zvinhu zvakakosha zvakaita seasidhi zvinhu uye catalyst yasara; inogona kunyatso kudzivirira kurasikirwa kwechiedza, kuputika, kupupa, kudonha uye kushanduka, nokudaro kuvandudza hupenyu hwebasa rejasi; shandisa ne ultraviolet absorbent kuti uwane zvirinani mamiriro ekunze anopikisa application kuita.
Inokodzera: zvipfeko zvemotokari, zvipfeko zvemabhizimisi, zvipfeko zvekushongedza uye matanda.
Wedzera huwandu: kazhinji 0.5-2.0%. Miedzo yakakodzera ichashandiswa kuona huwandu hwakakodzera hwakawedzerwa mukushandiswa kwacho.
Yakarongedzwa mu25 Kg / plastiki dhiramu kana 200 Kg / dhiramu.
Chengetedza munzvimbo inotonhorera, yakaoma uye ine mhepo.
