Could you share any details of this release agent? I'm looking for a method to bind two sheets of film in optical contact so that they can be released from each other easily. One sheet would be a processed sheet of slide film (screen-plate w/ TV-screen reseau) and the other would be a sheet of b&w film.

In old bi-pack & tri-packs there were patents and methods that used soap to bind the different layers. Right now I'm using gelatin w/ sorbitol which works, but is not yet ideal.
