   Such treatment is expected   
   to prevent inorganic or polar organic binding   
   to polar Si-OH groups.   
      
   For nonpolar organics, the effect may be the opposite,   
   binding organics to organic coating,   
   similar to a reverse phase chromatography.   
      
   For details how to, it may be preferred   
   to perform general internet search,   
   or get specialized literature.   
      
   What I heard, it is difficult   
   to reach professional quality in silanization   
   for critical application.
