Zinc Diecast

E-Kleen 125 — A powdered mixture of surface agents, detergents, suspension agents and buffers which is dissolved in water for the fast effective cleaning of copper, brass, steel and zinc diecast.

This highly buffered material is recommended as a heavy duty electrolytic and soak cleaner which will not attack zinc die-castings or slush castings.

It electrolytically removes smut while preventing the redeposition of soils and preparing the surface for electroplating.

E-Kleen 125 is the preferred soak cleaner to be used without an intervening water rinse prior to an electrolytic solution of E-Kleen 125.

It can also be used as an electrolytic or soak cleaner for copper, brass and steel.

E-Kleen 125 Operating Parameters – Electrolytically

Lower temperatures (140° to 160° F) may be required with copper and brass. There will be some mild oxidation (darkening) of the copper and brass surfaces during electrolytic cleaning. These oxides are easily removed with a short acid pickle prior to electroplating.

When used as a soak cleaner the concentration is maintained at 8 to 10 oz/gal. and temperatures in excess of 160°F. The required cleaning time will depend upon the type and degree of soil on the surfaces and on the concentration and temperature of the solution.

E-Kleen 173 — A Combination Electrolytic and Soak Cleaner for Zinc Diecastings as well as Copper, Brass and Steel.

E-Kleen 173 is a mildly alkaline powdered mixture of highly fortified surface active agents, detergents, suspension agents and builders which is dissolved in water for the fast, effective cleaning of metals.

E-Kleen 173 contains a chrome reducer.

E-Kleen 173 is recommended for applications where there is limited cleaning equipment — no secondary soak available. It is excellent for short cleaning cycles.

It is recommended as a cathodic cleaner for diecast zinc and white metal with a short current reversal to anodic just prior to removal of a rack.

It is an excellent cathodic cleaner for copper, brass and steel.

E-Kleen 173 removes light buffing compounds and light oils.

Benefits

• Long Life.
• Excellent chrome reducing properties which is advantageous when racks are not stripped.
• Free rinsing.
• Does not scum with hard water.
• Resists drying tendency with long transfer times when used at temperatures of 130° to 150° F

E-Kleen 174 — Is the recommended electrocleaner for use prior to plating zinc die castings with EPI’s E-Brite Ultra Cu alkaline non-cyanide copper plating process.

It is a mildly alkaline powdered mixture of highly fortified surface active agents, detergents, suspension agents and builders which is dissolved in water for the fast, effective cleaning of zinc die castings.

E-Kleen 174 is used as an anodic electrocleaner.

The very mild solution does not attack or discolor diecast zinc surfaces.  If contains a chrome reducer.

It may also be used as a soak cleaner prior to its use as an electrocleaner. An intervening cold water rinse is recommended but it is not mandatory.  It may also be used as a combination soak and electrocleaner in a single tank by soak cleaning for 5-10 minutes prior to turning on the current to electroclean for 1-2 minutes.
