Silane coupling agents ke mofuta oa metsoako ea silicon e nang le metsoako e 'meli e fapaneng ea lik'hemik'hale molek'huleng, e sebelisetsoang ho ntlafatsa matla a sebele a maqhama pakeng tsa li-polymers le thepa ea tlhaho.Sena se ka 'na sa bolela ho eketseha ha ho khomarela' nete, hammoho le ntlafatso ea ho nosetsa, thepa ea rheological, le lisebelisoa tse ling tsa ts'ebetso.Li-coupling agents li ka boela tsa ba le phello ea ho fetola sebaka sa sebopeho ho ntlafatsa moeli o pakeng tsa mekhahlelo ea tlhaho le ea tlhaho.
Ka hona,silane coupling agentsli sebelisoa haholo liindastering tse kang likhomaretsi, likoatipa le li-inks, rabara, casting, fiberglass, likhoele, masela, polasetiki, li-filler le kalafo ea holim'a metsi.
Sehlahisoa sa eona sa khale se ka emeloa ke mokhoa o akaretsang oa XSiR3, moo X e leng sehlopha se seng sa hydrolytic, se kenyeletsang lihlopha tsa alkenyl (haholo-holo Vi) le lihlopha tsa hydrocarbon tse nang le lihlopha tse sebetsang tse kang CI le NH2 qetellong, ke hore lihlopha tsa carbon functional;R ke sehlopha sa hydrolyzable, ho kenyelletsa OMe, OEt, joalo-joalo.
Lihlopha tse sebetsang tse nkiloeng ka X li na le tšekamelo ea ho itšoara ka lihlopha tse sebetsang ka har'a li-polymers tse phelang, tse kang OH, NH2, COOH, joalo-joalo, kahoo li kopanya silane le li-polymers tsa tlhaho;Ha sehlopha se sebetsang se sebelisoa ke hydrolyzed, Si-R e fetoloa ho Si-OH le lihlahisoa tse kang MeOH, EtOH, joalo-joalo li hlahisoa.Si OH e ka kena ka har'a condensation le dehydration reactions le Si OH ka limolek'hule tse ling kapa Si OH holim'a substrate e tšoaroang ho etsa li-bond tsa Si O-Si, esita le ho itšoara ka li-oxide tse itseng ho theha li-bond tse tsitsitseng tsa Si O, ho lumella.silaneho hokahana le disebediswa tsa inorganic kapa tsa tshepe.
