Zinc Plating

Zinc plating involves the electrolytic application of zinc by immersing clean steel parts in a zinc salt solution and applying an electric current. We carry six different zinc plating products that are sure to fit your metal plating needs. They include: E-Brite Ultra-Alk, an alkaline non-cyanide zinc plating process; E-Brite Ultra-Chlor AP, a mixed ammonium/potassium chloride bright zinc plating process; E-Brite Ultra-Chlor NA , a non-ammoniated bright chloride zinc plating process, E-Brite ZNI, a patented zinc-nickel alloy process which provides the corrosion resistance of cadmium, and E-Brite 400 a cyanide zinc brightener. Our zinc plating chemicals are suitable for rack or barrel plating and large volume batches. Call 262-786-9330 to order a sample of our zinc plating. Need more information about electro plating zinc?

E-Brite Ultra-Alk — Alkaline Non-Cyanide Zinc Plating

E-Brite Ultra-Alk is a thoroughly tested, stable and production proven zinc plating brightener process. It is suitable for either rack or barrel plating. E-Brite Ultra-Alk provides better zinc metal distribution than traditional alkaline zinc or chloride zinc plating systems. Operating parameters are wide and therefore it is an easy process to maintain.

E-Brite Ultra-Alk deposits are ultra bright and ductile over a wide current density range. It plates mirror bright to 120 ASF. The deposits readily accept all chromate conversion coatings. The process was developed to replace cyanide zinc plating without sacrificing the quality of the zinc deposit. Waste treatment is simplified and requires only a simple pH adjustment to precipitate zinc metal as zinc hydroxide.

Benefits of Zinc Plating:

Ultra bright zinc deposit. Approaching that of chloride zinc.
Excellent ductility & adhesion. Maintains ductility even with thicknesses in excess of one mil.
A low stress deposit.
Superior zinc deposit plate distribution.
Consistent distribution.
Excellent chromate conversion coating receptivity.
Zinc deposit appearance is comparable to cyanide or chloride zinc.
Operates within wide range of bath chemistry.
Temperature tolerance up to 120˚F, which reduces cooling costs.
Excellent brightener stability and brightener life of 30,000 amp hours.
Suitable for either rack or barrel plating.
Simple waste treatment procedure.
A reliable, easy to maintain process.
It contains no complexers or chelating agents.
It accepts all hexavalent and trivalent chromates.

E-Brite Ultra-Chlor AP - A mixed ammonium/potassium chloride bright zinc plating process
E-Brite Ultra-Chlor AP produces brilliant, level and ductile deposits even on difficult substrates such as cast iron, heat treated and carbonitrited steel.It produces better distribution than any other chloride process on the market. The water soluble brightener goes into solution much more readily than a solvent based brightener. Hydrochloric acid can be added directly to the bath without kicking out (oiling out) the brighteners because of the water solubility. The HCI does not destroy the additives.

Benefits of Zinc Plating Process - E-Brite Ultra-Chlor AP:

Excellent brightness in HCD and LCD.
No foam.
Water soluble brightener that goes into solution without oiling out.
30,000 to 40,000 amp hours per gallon brightener consumption.
Cloud point of 190˚F.
Wide operating window of operation.
Low organics concentration produces easier iron removal, ease of chromating, and easier rinsing.
Rack and barrel installation.
Good distribution.
Boric acid is not required.
Plates up to 130 ASF.
Operates as high as 120˚F.

E-Brite Ultra-Chlor NA - A non-ammoniated bright chloride zinc plating solution
E-Brite Ultra-Chlor NA has the same inherent advantages and benefits as E-Brite Ultra-Chlor AP but uses a different carrier component.

E-Brite 400
Cyanide zinc brightener that has good temperature stability and very wide plating range. It works in conventional and low concentration baths.

E-Brite ZNI - A patented zinc-nickel alloy process which provides the corrosion resistance of cadmium.
The unique benefit of the E-Brite ZNI deposit is it exhibits low hydrogen embrittling characteristics, making it ideal for many hydrogen embrittlement sensitive applications.

E-Brite ZNI employs a highly efficient, slightly acidic electrolyte (pH 6.3).
E-Brite ZNI deposit contains 8-12% nickel, the balance being zinc.
The patented microstructure facilitates migration of elemental hydrogen during a low bake temperature cycle.
Non-embrittling acceptable to ASTM F519 Type I, II, III, IV.
Corrosion resistance of chromate converted deposits have exceeded 2600 hour salt spray ASTM B117.
Conforms to AMS 2417 and Boeing BAC 5637.
