I-UV-123 iyisiqiniseko sokukhanya se-amine esinamandla, esine-alkaline ephansi, inganciphisa ukusabela ngezingxenye ze-asidi ohlelweni lokumboza, olufaneleka ngokukhethekile ohlelweni oluqukethe izinto ezikhethekile ezifana ne-asidi nensalela ye-catalyst; ingavimbela ngokuphumelelayo ukulahlekelwa ukukhanya, ukuqhekeka, ukugwedla, ukuwa nokushintsha umbala, ngaleyo ndlela kuthuthukise impilo yesevisi yokumboza; sebenzisa nge-ultraviolet absorbent ukuze uzuze ukusebenza okungcono kohlelo lokusebenza olumelana nesimo sezulu.
Ifanele: izigqoko zezimoto, izimbobo zezimboni, izigqoko zokuhlobisa kanye nezingubo zokhuni.
Engeza inani: ngokuvamile 0.5-2.0%. Izivivinyo ezifanele zizosetshenziswa ukuze kutholwe inani elifanele elingezwe ekusetshenzisweni okuthile.
Ipakishwe ku-25 Kg / isigubhu sepulasitiki noma ama-200 Kg / isigubhu.
Gcina endaweni epholile, eyomile futhi engenawo umoya.
