UV absorber UV-928 yog benzotriazole UV absorber, muaj peev xwm nqus tau 270-380 nm ultraviolet lub teeb, nrog lub ncov nqus ntawm 303 nm thiab 345 nm. Nws muaj cov yam ntxwv ntawm kev sib raug zoo, tsis tshua muaj hluav taws xob, zoo dispersion, tsis tshua muaj kev txav mus los, zoo thermal stability thiab siab nqus efficiency, thiab yog tsim rau kub curing system, hmoov txheej thiab dov steel txheej. Ua ke nrog lub teeb stabilizer UV292 thiab UV123, ua kom lub zog ruaj khov ntawm cov txheej txheem, thiab inhibit qhov txheej txheej ntawm lub teeb poob, discoloration, tawg, thiab delamination.
Feem ntau siv hauv: automotive txheej, coil txheej, hmoov txheej.
