Not to be arbitrarily negative, but why would you want to do that? The point of attaching silane groups to the PVA polymer is for good adhesion to glass. It realy dose work, and has been used for that purpose in all sorts of industrial application for many decades. As for PE's question about adhesion to film, IDK, and will let someone else find out. I live and breath glass. I wish that the entire planet and everything in it could be glass, and, like my heart,easily broken.
