ʻO ka UV absorber UV-928 he benzotriazole UV absorber, hiki ke hoʻopili i ka kukui ultraviolet 270-380 nm, me ka nui o ka absorption o 303 nm a me 345 nm. Loaʻa iā ia nā hiʻohiʻona o ka hoʻohālikelike maikaʻi, haʻahaʻa haʻahaʻa, hoʻopuehu maikaʻi, haʻahaʻa haʻahaʻa, kūpaʻa wela maikaʻi a me ka maikaʻi absorption kiʻekiʻe, a kūpono no ka ʻōnaehana hoʻōla wela kiʻekiʻe, ka uhi ʻana a me ka uhi kila. Hoʻohui pū ʻia me ka stabilizer māmā UV292 a me UV123, hoʻomaikaʻi nui i ka lōʻihi o ka uhi ʻana, a ke keʻakeʻa nei i ka nalowale o ka mālamalama uhi, discoloration, māwae, a me ka delamination.
Hoʻohana nui ʻia i: ka uhi ʻana o ka automotive, coil coating, powder coating.
Ka nui i manaʻo ʻia: 1.0-3.0%, ua hoʻoholo ʻia ka nui kikoʻī e like me ka hoʻāʻo noi noi mea kūʻai.
Hoʻopili ʻia i 20 a i ʻole 25 Kg / pahu pahu.
E mālama i kahi maloʻo a maloʻo; pale pololei i ka lā.
E ʻoluʻolu e kelepona mai iā mākou no nā palapala pili.
Hoʻolaʻa ʻia ʻo New Venture Enterprise i ka hoʻolako ʻana i nā stabilizer kukui kiʻekiʻe e hoʻokō i nā pono like ʻole o kēia mau ʻoihana, e hoʻokau i ka hana hou a me ka hoʻomau i ka hoʻomohala ʻana i nā huahana, e ʻoluʻolu e kelepona iā mākou:
