General Chemical’s line of
E-Coat Cleaners are water based, acidic materials
formulated to remove uncured cathodic electrostatic
paint build-up. These cleaners contain no chlorinated
solvents or anhydrous silica. They are non-toxic, low
odor materials that are used to clean heat exchanger
plates and tubes, tank walls, car carriers, pumps,
piping and spills on the floors as well as ultra
filtration systems.
Electro deposition works much like a plating process. The parts (cathode) to be coated serve as one electrode and the auxiliary electrodes (anode) serve as the oppositely charged pole as displayed by the following diagram.
Ineffective cleaning and membrane fouling
problems are not unusual. In e-coat operations. General Chemical
helps customers get the most from their Membranes by solving their
most complex cleaning and Fouling problems.
E-Coat Cleaner 1684 is a water based concentrated cleaner designed for use in a spray-recirculation system. It has been formulated to minimize foaming while effectively removing uncured E-Coat sludges.
E-Coat Cleaner-1910 SC is a water based mixture of selected organic components designed to provide effective removal of uncured electrostatic paint deposits.
E-Coat Cleaner 3555A and E-Coat Cleaner 3555B are components of a two part E-Coat cleaning system, that, when both are added to water, produce an effective means of dissolving uncured E-Coat.
E-Coat Cleaner-4770 is a thickened version of E-Coat Cleaner-1910 SC. It is water based, consisting of selected organic components designed to provide effective removal of uncured electrostatic paint deposits.
Adhesive Remover, Urethane Stripper, Epoxy
Paint Stripper, Ecoat and Powder Coat:
Stripoxy 6840 is used for the removal of
cured & uncured coatings from a variety of
substrates ESPECIALLY DESIGNED FOR ALUMINUM
AND NON FERROUS METALS yet safe on ferrous
metals.
Water Based E-coat paint Stripper and
Galvanized Paint Stripper For Soak Tanks.
For the removal of E-Coat Powder Coat from
Steel, Aluminum and Galvanized steel parts
without adversely affecting the galvanized
surfaces.
Inorganic foulants, heavy metals, oil and grease
will reduce membrane performance over
time. General Chemical’s e-coat membrane
cleaners are especially formulated to clean and
enhance the performance of tubular, spiral,
hollow-fiber and flat sheet configuration used
for microfiltration (MF), ultrafiltration (UF),
nanofiltration (NF) and reverse osmosis (RO)
membranes and enhance performance.
Standard Cathodic E-coat Element Cleaning Procedure Guidelines:
The mechanics of the cleaning procedure is generally the
same for most systems, the following procedure is
specific to the General Chemical e-coat Concentrate
cleaner chemistry. The procedure is based on cleaning
one eight inch or two six inch cartridges at a time with
an individual cartridge cleaning system. You should feel
free to modify the mechanics – not the chemistry – to
accommodate your specific cleaning system.
1. Isolate the cartridge to be cleaned from the paint
manifolds (feed, return, and permeate).
2. Initial Flush Procedure: Drain paint from the
cartridge and follow up with a D.I. water flush to
drain. Cartridge should be flushed until water runs
clear. If the flush is to be done using a tank and a
pump, adjust the pH to the paint tank (or lower) is
preferred.
3. Final Flush Procedure:
Fill: cleaning tank with D.I. water and adjust pH to
approximately 2.0 – 2.2
Open: cleaning return
Open: permeate to cleaning tank
Close: cleaning feed
Start Pump: slowly open the cleaning feed valve
Circulate pH adjusted D.I. water at ambient temperature
for about 5 minutes and drain. Close the cleaning inlet
valve. 4. Preparation of Cleaning Solution: Prepare a 200-liter
cleaning solution by mixing the cleaner in the cleaning
tank based on a 99:1 dilution. The 200-liter quantity is
based on the cleaning of one eight or two six nch
cartridge at a time. NOTE: Be sure to leave at least 20
cm of space at the top of the cleaning tank to
accommodate foaming. 5. Cleaning Procedure: Raise the temperature of the
cleaning solution to 100-105 degrees Fahrenheit either
by heating or closed loop circulation.
