Adox Adostab is an image silver stabilizer for black and white materials. Uses the same active ingredients as Agfa Sistan, but in revised proportions to achieve improved archival performance. Protects films and paper from changes in the silver image and for archival protection without altering the image tone. Sistan protects films and paper from changes in the silver image caused by UV light and 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.
Adostab is recommended as an alternative to Selenium toner for fine art printers who want added archival protection without altering the image tone of the print. A slight increase in density may occur. Adostab can also be used alongside Selenium toner for additional protection.
Apply Adostab like a wetting agent for 120 sec. There is no need to wash the print or film after use. Wipe dry and you're done.
