Crystalline Ferric Chloride solves very well in water - better than granules. Suitable for etching metals like copper, zinc, bronce, silver, brass and steel and pcbs in electronics.
Ferric Chloride is due to its properties the ideal etchant for metals and does not cause health damage if used appropriate.
Suitable for: tray, etching tank, spray etching tank
Ferric Chloride etches straight and precise
almost indefinitely shelf life - always keep it in a well closed container or else it will liquidify
very effective - 1 liter of Ferric solution is able to absorb up to 100 gram of solved metal
safe if used appropriate
no acid but a corrosive salt
Consistency: crystalline sandy and lumpy
for a strong etchant the compound is mixed in a ratio of 1 to 1 with water ( e.g. 1 kilogram Ferric Cloride + 1 liter water)
more subtle works may be etched in a thinned solution of up to 1 to 4 ( e.g. 1 kilogram Ferric Cloride + 4 liter water)
the ideal fast etching temperature is around 47 degree centigrade but works already at room temperature
stainless steel requires a warmed etching bath
the etchant should be in steady movement to prevent the slurry which is produced during etching to sink into the lines
Safety and disposal:
take the usual precautions when working with chemicals: safety glasses, safety gloves, and safety dress
when preparing the solution good aeration or an exhaust hood is required
avoid direct skin and eye contact and do not inhale fumes
store in plastic or glass container. Do not use any metal containers
used solution may not be disposed in the sewer system
