It wouldn't work for me, but then I was working from what little information
I could scrounge on the web, and with the advice of some people that,
admittedly, are not experts on using coupling agents. Perhaps you could
point me to some better information?
When I added the opoxysilane to my gum emulsion, the emulsion, A) tended to
bead up on the glass or metal surface and no amount of brushing would smooth
it out (even when I added various surficants), and B) took many hours to
dry.

Hi,
I just want to insist on the fact that the DOW Corning z-6040 epoxysilane is
OK to have your emulsion stick to a clean glass surface. This is a fully
transparent clean product. One part of that molecule sticks to the glass.
The other part reacts with the gelatin and is attached chemicaly to it. The
result is a strong bound to the glass surface.
