The photostabilizer UV770 ke boima bo tlaase ba molek'hule bo sitisang amine photostabilizer, e nang le litšobotsi tsa ho lumellana hantle, ho fokotseha ho fokolang, ho hasana hantle, ho tsamaea ka tlaase, botsitso bo botle ba mocheso le botsitso bo phahameng ba optical, 'me ha e amohele leseli le bonahalang' me ha e ame mmala. Bakeng sa karolo e phahameng le e teteaneng ea sehlopha se moqotetsane, ho bopa, ho na le photostability e babatsehang. Ka matla a phahameng a limolek'hule tsa boima ba "stabilizer" le "ultraviolet absorber", phello ea synergistic e bohlokoa.
Haholo-holo e sebetsang ho: polyethylene, polypropylene, polystyrene, olefin copolymer, polyester, polyvinyl chloride e bonolo, polyurethane, polyformaldehyde le polyamides, li-adhesives le litiiso joalo-joalo.
Chelete e khothaletsoang ea tlatsetso: ka kakaretso 0.05-0.60%. Liteko tse nepahetseng li tla sebelisoa ho fumana chelete e nepahetseng e kentsoeng ts'ebelisong e itseng.
E pakiloeng ka 25 Kg / lebokose. Kapa e tletse ho latela litlhoko tsa bareki.
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 HALS ea 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:
