This is an image silver stabilizer for black and white materials. SISTAN protects films and paper from changes in the silver image caused by environmental effects. These faults initially appear as reddish to yellowish-brown highlight discolorations, and the complete negative may be destroyed by the silver being converted to a colloidal form. Its causes are industrial and traffic fumes, and fumes from heating oil, plastic paints, compressed boarding, cardboard with an acid content, glues, sticky tape, freshly cut PVC and brittle rubber, and also ozone and all substances giving off peroxide.
