Wakiilada isku xidhka Silane waa nooc ka mid ah xeryahooda silikoon organic ka kooban laba siyood oo kiimiko ah oo kala duwan oo ku jira molecule, oo loo isticmaalo in lagu hagaajiyo xoogga isku xidhka dhabta ah ee u dhexeeya polymers iyo alaabta aan dabiiciga ahayn.Tani waxay tixraaci kartaa kororka ku dheggan dhabta ah, iyo sidoo kale hagaajinta qoynta, sifooyinka rheological, iyo sifooyinka kale ee hawlgalka.Wakiilada isku xidhka ayaa laga yaabaa inay sidoo kale wax ka beddelaan aagga is-dhexgalka si kor loogu qaado lakabka xadka ee u dhexeeya wejiyada organic iyo kuwa aan noolaha ahayn.
Sidaa darteed,wakiilada isku xidhka silanewaxaa si weyn loogu isticmaalaa warshadaha sida xabagta, dahaarka iyo khadadka, caagga, shubista, fiberglass, fiilooyinka, dunta, balaastikada, buuxinta, iyo daaweynta dusha.
Wax soo saarkeeda caadiga ah waxaa lagu matali karaa qaabka guud ee XSiR3, halkaasoo X ay tahay koox aan hydrolytic ahayn, oo ay ku jiraan kooxaha alkenyl (badanaa Vi) iyo kooxaha hydrocarbon oo leh kooxo shaqeynaya sida CI iyo NH2 dhamaadka, ie kooxaha shaqeeya kaarboon;R waa koox hydrolyzable ah, oo ay ku jiraan OMe, OEt, iwm.
Kooxaha shaqada ee lagu qaado X waxay u nugul yihiin inay la falgalaan kooxaha shaqaynaya ee polymers organic, sida OH, NH2, COOH, iwm.Marka kooxda shaqaynaysa la hydrolyzed, Si-R waxaa loo beddelaa Si-OH iyo by-products sida MeOH, EtOH, iwm. ayaa la soo saaray.Si OH waxa ay mari kartaa falcelinta uumiga iyo fuuq-baxa Si OH ee molecules kale ama Si OH oogada substrate-ka la daweeyay si loo sameeyo curaarta Si O-Si, oo xataa la falgasho oksidhooyin gaar ah si ay u sameeyaan xidhidh Si O deggan, taas oo u ogolaanaysasilaanyoin lagu xidho walxaha aan organic ama biraha ahayn.
