This is a shameless cross post from the same question on Photrio: https://www.photrio.com/forum/threads/subbing-siliconized-bo-pet-mylar-estar-film-for-gelatin-adhesion.193350/unread
My apologies for any who come across this twice, but my estimate is that there's going to be just a handful of people across both forums who are likely to have good suggestions on this (bad ones are nonetheless also welcome - seriously, don't hold back).
To summarize from the thread linked above: I've got this roll of silicon coated (both sides) Mylar (officially BoPET, which is basically Melinex or the base material of Estar as well) which I'd like to use as temporary support for carbon tissue. Since it's phenomenally water-repellant, I'm looking for a way to sub it so that carbon tissue will stick to it.
I tried dilute gum arabic, but anything water-based just beads on the surface. Dragging a sheet through a tray with subbing solution doesn't work.
Has anyone dealt with this before?
PS: yes, I know fixed out silver gelatin paper works fine as a temporary support, as do a variety of other materials, and your suggestions are certainly welcome, but the gist of this question is how I can use this particular material in this particular application.
