Sigma-Aldrich will "take you to the cleaner`s" They do with all chemicals and are a "last resort". B&S get their amino-silane from HIS Glassworks. You can buy it directly from HIS G.
Their are silanes made with all of the standard active groups, including epoxy,di-amine and on and on. The Chinese get realy creative with them.
Go to Union Carbide and/or Dow Cemical 9or Dow Corning, I forget which) For an assortment of these little miricles of modern chemistry.
The way in which I use amino-silane is not to paint glass with it. I do a controled chemical reaction under a fume hood. I stoped applying it directly to glass a long time ago. That method works sometimes and sometimes not.
I agree with Ron. There are better ways to prevent frilling and emulsion lifting from glass. The best of which is proper cleaning of the glass.
I am not doing carbon right now, but my friend who dose carbon on glass dumps a s**t-load of 5% amino -silsne on the glass. He used 4 coats without whipeing. He gets good results that way. But I think that even he has abandoned silane in favore of other things.
