ElectroPolish NR™ RDZ-1960

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.

ChemPolish™ SS RDZ-1815

A System for Chemical Polishing 300 Series Stainless Steel RDZ-1815

ChemPolish SS™ (RDZ-1815) is an acidic bath used for cleaning, polishing and passivating 300 Series (austenitic) Stainless Steel to render it suitable for use in extreme environments (such as high vacuum, medical or aerospace applications). ChemPolish SS™ (RDZ-1815) leaves a brilliant specular finish, free of etching, hydrogen embrittlement, or halide-induced stress cracking. The surface is cleaned completely of any organic contamination, is free of soluble inorganic residues and has highly reduced particulate count. ChemPolish SS™ (RDZ-1815) gives maximum brilliance with minimum material loss, approximately 0.0001 inch (1/10 mil) per minute.

PRE-TREATMENT:
ChemPolish SS™ (RDZ-1815) is preceded by a cleaner, ideally MicroClean Ti™ (RDZ-1849), followed by a rinse. If weld scale is present after cleaning, the part should be treated in Alkaline Descale (RDZ-1734) for 90 minutes at 200°+ F, followed by a water rinse and a 30-second dip in Descale Remover (RDZ-1735). This removes the weld scale and prepares the surface for a uniform chemical polish (see Product Data Sheet for Alkaline Descale).

MAKE-UP:
ChemPolish SS™ (RDZ-1815) is used as supplied at 175 ± 5° F for 2 to 5 minutes (typically). IMPORTANT: DO NOT allow bath temperature to fall below 170°F.

OPERATION:
ChemPolish SS™ (RDZ-1815) may be controlled/monitored by titration, or specific gravity, or color. Certain alloys (especially high carbon) of Stainless may raise a black smut while being polished. This can be removed by a short (30-180 second) dip in room temperature 50% Nitric acid.

EQUIPMENT:
Very ruggedly constructed polypropylene tanks, reinforced for high-temperature use, are required. Teflon or PVDF may be used, but these are usually too costly. Teflon steam coils are the best method of heating the bath. Quartz electrical heaters may also be used. However, some form of mild agitation to keep the solution moving over heaters is recommended. This prevents localized overheating and minimizes brightener decomposition.

DISPOSAL:
ChemPolish SS™ (RDZ-1815) is strongly acidic:
used solutions will contain dissolved nickel and chrome metals that will precipitate when neutralized to pH 9.0. Dispose of in accordance with Federal, State and local regulations. Contact your RD Chemical representative for further information.

RD Chemical Company makes these recommendations in good faith, based on laboratory and field testing. Ultimate responsibility for propriety of use, however, must rest with the purchaser and user. RD Chemical Company recommends thorough testing of its products, before use.

SAFETY:

Caution should be exercised in handling ChemPolish SS™ (RDZ-1815) or any of the additives. The ChemPolish SS™ (RDZ-1815) system is highly acidic and will cause permanent eye damage if contact is made and may cause skin lesions if not washed off promptly. Accordingly, it is important to wear complete eye protection and clothing that is resistant to dilute acids when working with ChemPolish SS™ (RDZ-1815) or the additives. When the ChemPolish SS™ (RDZ-1815) bath is in operation, it gives off various oxides of nitrogen and other acidic gases. Therefore, a ventilation system capable of providing airflow of 75 feet per minute away from the operator is required. This will necessitate between 100 and 800 cubic feet per minute airflow for each lineal foot of operating side of the tank, depending upon the design of tank and ducting. Consult Material Safety Data Sheet for further information.

MicroClean™ BS RDZ-1816

De-Oxidizer for Nitinol

A deoxidizer for removing extreme oxides formed by high temperature on Nitinol, and other Titanium alloys. MicroClean™ BS (RDZ-1816)will cause some low level metal attack, but usually will clean up essentially any oxide level in a short time (1-5 minutes) and metal loss within this time is minimal. If any metal loss is not acceptable, use MicroClean™ Ti (RDZ-1849), which will deoxidize much more slowly, but will give zero metal attack.

MAKE-UP:
Use as received, do not dilute. May be used at room temperature, or heated. There is no maximum temperature. Higher temperatures result in more rapid deoxidation, and metal loss.

OPERATION:
Immerse parts in solution, agitation will speed oxide removal. Ideal operation is to treat parts in MicroClean™ BS (RDZ-1816) , then rinse rapidly in water, and do final treatment/deoxidize in MicroClean™ Ti (RDZ-1849). Then rinse.

EQUIPMENT:
Use/store only in plastic containers, will attack most metals and glass.

SAFETY:
