UV-928 e monyang UV-928 ke benzotriazole UV e monyang, e khonang ho monya khanya ea 270-380 nm ea ultraviolet, e nang le sekhahla se phahameng sa ho monya sa 303 nm le 345 nm. E na le litšoaneleho tsa ho lumellana hantle, ho hloka botsitso, ho hasana hantle, ho tsamaea ho tlaase, botsitso bo botle ba mocheso le bokhoni bo phahameng ba ho monya, 'me e loketse tsamaiso ea mocheso o phahameng oa mocheso, ho roala phofo le ho roala tšepe. Ha e kopantsoe le khanya e tsitsitseng ea UV292 le UV123, e ntlafatsa haholo ho tšoarella ha koae, 'me e thibela tahlehelo ea khanya ea mabone, ho fifala, ho phatloha le ho putlama.
Haholo-holo e sebelisoa ho: ho roala likoloi, ho roala li-coil, ho roala ka phofo.
Chelete e khothalelitsoeng: 1.0-3.0%, chelete e ikhethileng e khethoa ho latela tlhahlobo ea kopo ea bareki
E pakiloeng ka 20 kapa 25 Kg / lebokose.
Boloka sebakeng se pholileng, se omeletseng le se nang le moea; qoba letsatsi le otlolohileng.
Ka kopo ikopanye le rona bakeng sa litokomane life kapa life tse amanang.
New Venture Enterprise e ikemiselitse ho fana ka li-stabilizer tsa boleng bo holimo ho fihlela litlhoko tse fapaneng tsa liindasteri tsena, ho tsamaisa boqapi le botsitso nts'etsopele ea lihlahisoa, ka kopo ikopanye le rona:
