These groups can be the same or different and nonreactive or reactive, with the reactivity being inorganic or organic. Inorganic reactive silanes have alkoxysilane groups and undergo hydrolytic polycondensation reactions. Organic reactive silanes contain amine, vinyl, epoxy, isocyanate or other functional groups that enable reactions with organic functionalities. for more visit here- http://bit.ly/2Dlgopf
