E-Kleen
120
— Heavy duty, strong alkaline, highly conductive reverse current
cleaner for steel. Granular mixture used at 8 to 16 oz/gal. Temperature
180° to 200°F. Current density of 50 to 140 amps/sq.ft. at 4 to
6 volts.
It also makes an excellent soak cleaner because it is very free
rinsing, effective in hard water, and buffered to maintain its alkalinity
for long solution life. It is the preferred soak cleaner to be used
without an intervening water rinse prior to an electrolytic solution
of E-Kleen 120.

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

Density: |
10
to 30 asf zinc, copper
50 to 100 asf steel |
|
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
127 —
A unique liquid concentrate of surfactant and caustic for anodic
(reverse) electrocleaning and effective soak cleaning for steel.
Contains no phosphates, chelators or silicates. It has the unique
characteristic for a liquid sodium hydroxide formulation of being
freezable without having the typical crystallization problems. It
thaws out at room temperature. Emulsifies oils when used as a soak
cleaner. Concentration: 5 to 12% by volume in water. Temperature:
140° to 200° F. Rack Cleaning: 5 to 6 volts at 15 to 80 amps/sq.ft.
Barrel Cleaning: 12 to 15 volts at 20 to 30 amps/sq.ft. |

129 —
Heavy duty granular product formulated for anodic electrocleaning
and smut removal on steel and copper. It is non-phosphated, non-chelated
and offers a controlled foam blanket during electrocleaning. It
offers high conductivity with heavy soil loading capacity. It works
effectively to remove loose carbon smut and metallic oxide from
steel surfaces following acid pickling. Used at 8 to 10 oz.gal.
at 160° to 200° F to current density of 50 to 100 amps/sq.ft. at
4 to 6 volts for 1 to 2 minutes.

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.

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.
