NuGenTec EP 316:  Medical Device Electro Polishing Process Chemical (pdf file)  (MSDS)

Applications & Description:  Electropolishing removes metal from the surface producing a unidirectional pattern that is stress-free, microscopically smooth and often highly reflective.  In addition, improved corrosion resistance and passivity are achieved on many ferrous and some non-ferrous alloys. This process is used for micro- and macro-deburring, as the reverse plating process (electropolishing) removes metal ions from the high points on the surface without etching.  Unlike conventional mechanical finishing systems, the electropolishing does not smear, bend, stress or fracture the crystalline metal surface to achieve smoothness and/or luster.

Process:

1. Clean using alkaline cleaner (NuGenTec NuWet DM 41) and Rinse
2. Deoxidize / de-scale / acid pickle (NuBrite C 35, 50 or NuWet DS 105) and Rinse à Optional step
3. Electro-polish and Rinse
4. Nitric acid dip  and Rinse à Optional step
5. Hot Rinse (Using DI water for spot free drying) or Forced Hot Air Drying
