UV absorber UV-928 o se benzotriazole UV absorber, e mafai ona mitiia 270-380 nm ultraviolet malamalama, faatasi ai ma le maualuga absorption fua faatatau o le 303 nm ma le 345 nm. O loʻo i ai uiga o le fetaui lelei, maualalo le vaʻaia, faʻasalalau lelei, maualalo le feoaʻi, faʻamautu lelei vevela ma le maualuga o le absorption, ma e talafeagai mo le faʻamaloloina o le vevela, faʻapipiʻiina o le paʻu ma le paʻu uamea taʻavale. Faʻatasi ma le UV292 ma le UV123 stabilizer malamalama, faʻaleleia atili le tumau o le faʻapipiʻiina, ma faʻalavelaveina le gau o le moli, faʻafefeteina, taʻe, ma le delamination.
Fa'aaoga masani i: ta'avale ta'avale, fa'apipi'i vili, pa'u pa'u.
Fautuaina le aofaʻi: 1.0-3.0%, o le aofaʻi faʻapitoa e fuafua e tusa ai ma le suʻega talosaga a le tagata faʻatau
Faʻapipiʻi i le 20 poʻo le 25 Kg / pusa.
Teu i totonu o se nofoaga malulu, matutu ma fa'afefe; aloese mai le susulu o le la.
Fa'amolemole fa'afeso'ota'i matou mo so'o se pepa fa'atatau.
New Venture Enterprise ua faʻamaoni i le tuʻuina atu o faʻamautu malamalama maualuga e faʻafetaui ai manaʻoga eseese o nei alamanuia, faʻamalosia le faʻafouina ma le faʻaauau i le atinaʻeina o oloa, faʻamolemole faʻafesoʻotaʻi matou:
