PCS 333 - Hot Immersion Paint Stripper (Non-Methylene Chloride)

£0.00

PCS 333


1.0 Scope
PCS 333 is a non Methylene Chloride hot immersion paint stripper designed to remove wet paint and
powder coatings from a variety of substrates. The process minimises the attack on base metals such
as aluminium and its alloys and magnesium alloys.


2.0 Materials
PCS 333 IMU
PCS 333 A
0.1N Hydrochloric Acid
Phenolphthalein Indicator


3.0 Equipment
All equipment for use with PCS 333 should be constructed of 304 grade stainless steel which
minimises sludge formation on the walls and base of the tank. The surface area of the striping tank
should to be kept to the practical minimum to avoid solution losses. The tank should, ideally,
include circulation using educters to enhance the turnover rate and optimise stripping efficiency.
The heating system should be designed to maintain the required temperature and again ideally be
indirect side heating such as an oil jacket. This provides consistent heating with a large heat
exchange area reducing the likelihood of isolated hot spots. Low density electrical heaters may be
used however the cold length should extend at least 200 mm into the stripper solution and they
should be easily removable. Generally, though, immersion heating is not recommended as paint
residues can build up on the elements and cause element failure or lead to paint charring which can
give off undesirable fumes and odours.
To maintain process efficiency, it is beneficial to have some form of sludge removal system
incorporated into the tank. The preferred method is to have an in-line bag or cartridge filter fitted in
the circulation system.
All seals and gaskets should be PTFE and Viton must not be used under any circumstances.
Pressure washing can be used to remove the paint residues, especially in inaccessible areas. Rinse
tanks, if required, can be fabricated from mild steel and it may prove beneficial to include a spray
ring to improve rinsing.
A final rinse can be heated, if required, to aid component dry off and prevent flash rusting in the
case of steel being stripped.
Local Exhaust Ventilation is recommended in tank areas to efficiently remove any fumes and vapours
resulting from paint stripping application.


4.0 Method of operation
The PCS 333 is supplied ready for use with no dilution or addition required. The PCS 333 is operated
between 60 and 75deg C and the stripping time will depend upon the paint type and film thickness.
The paint / powder coating is removed from the wheel in small flakes/sheets/strips and to aid
filtration these can be manually removed by regular skimming of the tank surface using a stainless
steel mesh basket.
Following stripping in PCS 333 the components are pressure washed or rinsed with either one or two
rinses. In the event that two rinses are used the second rinse may be heated to air dry off and
reduce the risk of corrosion. If required Performance Chemicals can provide inhibitors for the final
rinse to stop corrosion of ferrous substrates.


5.0 Tank Management
In order to maintain effective stripping the tank must be monitored daily to ensure the chemical is at
the desired strength and the tank is free from paint residue which can cause a sludge precipitate if
left unmanaged causing particular problems for bottom heated tanks. It is therefore recommended
that in addition to the daily chemical checks outlined in the control section below that weekly
inspections of the tank are made to check the cleanliness of the tank. It may be necessary to
periodically drain and desludge the tank.


6.0 Control and testing
Daily control of the tank is essential to maintain stripping performance, PCS 333 is consumed during
the stripping process and it is important to replenish tank. In order to maintain efficiency and
optimum stripping performance it is recommended to top up as follows:
PCS 333 top up (litres) = Sets of wheels processed x 2.5
Water top up (litres) = Volume Lost - PCS 333 top up
All filtration and desludging losses should be made up using PCS 333.
Testing is undertaken to monitor and control the accelerator content. Under normal conditions the
PCS 333R will maintain the accelerator pointage however under certain circumtances it will be
necesary to raise the accelerator pointage with the addition of PCS 333A.
Prior to undertaking the accelerator pointage test it is advisable to top up the tank with PCS 333R as
required. Leave to mix for 10 minutes. Take a two ml sample of the tank working solution and add
10ml of water. Add five drops of phenolphthalein and titrate with 0.1N hydrochloric acid from a
pink colouration to a clear solution. The number of mls of 0.1N hydrochloric acid used is referred to
as the accelerator pointage.


7.0 Effluent
PCS 333 Solution must not be discharged to main drainage or storm drainage under any account.
The rinse waters should be allowed to run to a settling tank, where heavy solvent and paint residues
can settle. A registered Waste Disposal Contractor must dispose of heavy residues together with the
main solution.


8.0 Safety Precautions
When handling PCS 333 wear nitrile rubber gloves, pvc apron, rubber boots and full face protection.
Local Exhaust Ventilation is recommended to remove any fumes generated.
Smoking must be prohibited in the vicinity of the PCS 333 plant.
Full information on the hazards and safe handling of the material as supplied is given in the Health
and Safety Data Sheet. This must be read and understood fully by those handling or using the
product.
