Ferric chloride resist for copper etching



(-----) 2007

I'm trying to do some copper plate etching by screen printing a pattern to be preserved in a bath of ferric chloride. my chemicals doesn't sell the resist solution only producing it on prefabricated boards, can anyone recommend a liquid that would dry on the copper in a screen printing process. hopefully not toxic to the breath and preserve it in the acid bath...and perhaps another chemical bath that would help dissolve said resist after the process is done

I'd start with Lacquer based paints first, as they can be stripped using lacquer thinner [affil. link to info/product on Amazon] . Screen printing does require thick pastes typically to produce the pattern, so lacquers can be purchased very thick. Check your local art supply stores.
I know for a fact that Sharpies (Indelible ink permanent markers) work great to make repairs to patterned traces in ferric chloride.

Try a lacquer based on polyvinyl alcohol; it should resist ferric chloride solution and can be made photosensitive to create a photoresist. The unexposed material is soluble in water and the exposed parts come off in alkaline stripper
