archival adhesive for cyanotype?

Does anyone know of an adhesive that is safe to use (archival) with cyanotype on any specific paper combination? The adhesive would be applied to the back of the print, in just a small area near the center of the paper, to "float" it off the surface of a matte.

In other words, is there a combination of paper and adhesive that is not likely to damage the cyanotype? Or perhaps a paper of a very heavy weight? Or a way to treat the back of a paper before applying an adhesive? Would an acrylic medium be safe, if it worked?
