ElectroPolish for Chromium alloys

ElectroPolish NR will polish Chrome alloys, to a gleaming, specular, smooth surface, in minimum time, and with minimal metal loss. ElectroPolish NR polishes more smoothly, and with less metal loss than conventional electroPolishes. For best results, pre-clean and deoxidize parts to insure completely clean surface, followed with a water rinse, then an Isopropyl Alcohol rinse, then into ElectroPolish NR.

MAKE-UP: Use as received, do not allow to be contaminated with water.  Use at room temperature.

OPERATION: Voltage required is determined by anode/cathode distance.  If anode/cathode distance is even a few centimeters, very high voltages may be required to get polishing to occur. Depending on placement of cathode, voltages over 40 volts may be needed. Solution agitation will lower voltage requirements somewhat.  Extremely high current density (300+ ASF ≈ 30 Amp/dm2) has produced excellent results.  Cover bath when not in use to minimize water pickup. 

Metal Polished        Metal loss per amp.minute
304 Stainless Steel     75 milligrams

EQUIPMENT: ElectroPolish NR is not combustible, but under use, will warm rapidly.    For best results, keep bath under 90° F (32° C).  Heavy use will require cooling to keep bath temperature under control.   Cooling may be done with cold water circulating in Copper tubing coiled in bath.

SAFETY: ElectroPolish NR is non-hazardous, non-regulated as received.  However during use, it will pick up dissolved heavy metals.  Workers should be protected from exposure with Neoprene rubber clothing, and full-face shield, or splash goggles.  Consult Material Safety Data Sheet for further information.

DISPOSAL: Used ElectroPolish NR may contain heavy metals that which need to be removed before disposal.  If no heavy metals are involved, simple dilution is usually enough for most sanitary districts.  Dispose of in accordance with Federal, State and local regulations.  Contact your RD Chemical representative for further information.

PACKAGING: 4 liter bottles, 20 liter, 200 liter drums.
