Sistan is a stabilisor for black and white film and paper. Over time, the silver image is susceptable to traffic fumes, fumes from paint, card and paper which is not acid free etc. gradually the image on either film or paper may be destroyed as the silver is converted to a different form. Sistan protects against this. It contains potassium thiocyanate, a reacting stabiliser. This reagent converts residual silver halides that remain after fixing process into inert water-soluble silver complexes that are stable to heat and light.
