Special substance (adhesive or paint)

[lawrence]

Hi !

Can you recommend me a glue or paint or other chemical substance with the following properties:
- should be transparent
-should have a refr. index less than 1.6
-could be easily peeled off from glass
- should not dissolve in the same substance after drying (I want to make a thin film, peel it off and then stick it with the same substance to an optical device, but the film should not destroy)
-it is preferably but not mandatory that it should not dissolve in water

Thank you!

Maybe clear epoxy resin. RI = 1.5x

The clear part of a two part epoxy can make a good optical grease.

You may need to use a film or release agent when casting on a glass surface.
