Silane coupling agents imhando yeorganic silicon makomisheni ane maviri akasiyana emakemikari zvimiro mumorekuru, anoshandiswa kuvandudza iyo chaiyo yekubatanidza simba pakati pemapolymer uye inorganic zvinhu. Izvi zvinogona kureva kuwedzera kwekunamatira kwechokwadi, pamwe nekuvandudzwa kwekunyorova, rheological properties, uye zvimwe zvekushandisa. Coupling agents anogona zvakare kuve nekugadzirisa mhedzisiro panzvimbo yeinterface kuti awedzere muganho pakati pe organic uye inorganic zvikamu.
Naizvozvo,silane coupling agentsanoshandiswa zvakanyanya mumaindasitiri akadai seanonamira, machira neingi, rabha, casting, fiberglass, tambo, machira, mapurasitiki, mafirita, uye pamusoro pekurapa.
Chigadzirwa chayo chekare chinogona kumiririrwa neyakajairwa formula XSiR3, apo X iboka risiri hydrolytic, rinosanganisira alkenyl mapoka (kunyanya Vi) uye hydrocarbon mapoka ane anoshanda mapoka akadai CI uye NH2 pakupedzisira, kureva kabhoni inoshanda mapoka; R iboka rinogona hydrolyzable, kusanganisira OMe, OEt, nezvimwe.
Mapoka anoshanda akatakurwa muX anowanzoita nemapoka anoshanda mune organic polymers, akadai OH, NH2, COOH, nezvimwewo, nokudaro achibatanidza silane uye organic polymers; Apo boka rinoshanda rinoshandiswa hydrolyzed, Si-R inoshandurwa kuva Si-OH uye ne-zvigadzirwa zvakadai seMeOH, EtOH, nezvimwe zvinogadzirwa. Si OH inogona kuita condensation uye dehydration reactions neSi OH mune mamwe mamorekuru kana Si OH pamusoro peiyo yakarapwa substrate kuumba Si O-Si zvisungo, uye kunyange kuita nemamwe maokisijeni kuumba yakagadzikana Si O zvisungo, zvichibvumira.silanekubatanidza neinorganic kana simbi zvinhu.
