Nuugista UV-928 waa nuugeeyaha benzotriazole UV, oo awood u leh inuu nuugo iftiinka 270-380 nm ultraviolet, oo leh heerka nuugista ugu sarreysa ee 303 nm iyo 345 nm. Waxay leedahay sifooyinka iswaafajinta wanaagsan, isbedbeddelka hooseeya, kala firidhsan wanaagsan, dhaqdhaqaaqa hooseeya, xasilloonida kulaylka wanaagsan iyo waxtarka nuugista sare, waxayna ku habboon tahay nidaamka heerkulka sare ee daaweynta, daboolka budada iyo duubista birta duuban. Marka lagu daro xasiliyaha iftiinka UV292 iyo UV123, waxay si weyn u wanaajisaa cimriga dahaarka, waxayna ka hortagtaa luminta iftiinka dahaarka, midabka, dildilaaca, iyo delamination.
Inta badan loo isticmaalo: daahan baabuurta, daahan gariiradda, daahan budo.
Qadarka lagu taliyay: 1.0-3.0%, qadarka gaarka ah waxaa lagu go'aamiyaa iyadoo loo eegayo imtixaanka codsiga macaamiisha
Waxaa lagu soo buuxiyay 20 ama 25 Kg/ kartoon.
Ku kaydi meel qabow, qalalan oo hawo leh; iska ilaali iftiinka qorraxda tooska ah.
Fadlan nala soo xidhiidh wixii dukumeenti ah ee la xidhiidha.
New Venture Enterprise waxay u heellan tahay inay bixiso xasiliyeyaal iftiin tayo sare leh si ay u daboolaan baahiyaha kala duwan ee warshadahan, hal-abuurnimada wadista iyo joogtaynta horumarinta alaabta, fadlan nala soo xidhiidh:
