ARDROX 2320 is a di-phase aqueous blend of solvent, activators and corrosion inhibitor.
ARDROX 2320 will remove a variety of organic finishes.

Chemicals required

Method of use
Half fill the stripping tank with demineralised water. Add 10% v/v, of the operating volume,
ARDROX 2320A. Add 5% v/v of ARDROX 2320B. Thoroughly agitate. Fill the tank to its operating level
with demineralised water and thoroughly agitate the contents of tank.
Components to be stripped are immersed in the bath for periods generally up to 4 hours at temperatures
from ambient to 55°C depending on the nature of the coating. The bath should be agitated while the
components are in the tank. The components are then pressure water rinsed.
Components should be left in the spray machine for periods generally up to one hour at temperatures of
ambient to 55°C. If possible a two-stage spray machine should be used so the components can be water
rinsed within the spray machine. If this is not possible the components should be pressure rinsed outside
the cabinet.
Dry the components thoroughly using compressed air or an air recirculation oven at 60 - 80°C.
NOTE Ardrox 2320 can be used at higher temperatures on non-critical components that are not
susceptible to hydrogen embrittlement.

Method of control
The pH of the water phase (top phase) of the bath should be maintained within the range 12.-12.5. To
raise the pH of the bath add ARDROX 2320B in measured increments until within the desired range.
The lower phase of the bath (ARDROX 2320A) should be maintained within the range 5-15% v/v. This
may be measured by taking a representative sample of the tank contents, placing in a measuring
cylinder and allow to stand. If the lower separated phase is below the desired range add ARDROX
2320A, if above the range add demineralised water.
Any water added to the tank to correct for evaporation should be demineralised water.

Effects on materials
Will not affect most common metals, e.g steel, zinc, aluminium, copper. Polymeric materials, such as
Perspex/Plexiglas (polymethylmethacrylate) and PVC, and some rubbers will be affected.
