This research project investigates face-mounting processes for colour photographs that use an acetic acid curing, one-part silicone sealant to permanently adhere the emulsion side of a print to a sheet of poly(methyl methacrylate). The original procedure was patented in the early 1970's under the name of Diasec by its Swiss inventor Heinz Sovilla-Bruhlhardt, and has since caused imitators to develop similar processes. The stability of prints mounted in this fashion compared with that of unmounted prints has not yet been examined or tested in any published studies. In this project, samples of both unmounted and facemounted prints from three laboratories, which use different sets of silicone sealant and primer coating as well as double-sided adhesive film, were subjected to an analysis of their physical structure.
