DESCRIPTION
A8901W/03308
Ardrox 8901W is a suspension of white pigment in a resin base, which utilizes a fast drying,
solvent system to facilitate speed and ease of application.
USES
Ardrox 8901W is used in conjunction with the Ardrox visible magnetic particle inspection
processes. It provides an excellent contrasting white background when dark steels are being
tested. Ardrox 8901W provides a matt finish which assists the viewing of defects due to the
lack of reflections produced.
The smooth surface finish provided by this product allows the magnetic ink to remain
mobile on the surface for longer, thus assisting the detection of the defects.
APPROVALS
When sprayed to a minimum dry film thickness of 25 microns, Ardrox 8901W conforms to
the requirements of BS 5044, “Contrast Aid Paint Used In Magnetic Particle Flaw Detection”.
Surface drying time classification is category A. Classification of paint by flash point –
highly flammable.
METHOD OF USE
The metal surface is first cleaned to remove rust, scale paint or other contaminants. If water
is used in the process, ensure the component is dried. The final cleaning operation should be
to degrease the surface using Ardrox 9PR50C, then allow it to flash dry.
Ardrox 8901W is then sprayed directly from an aerosol (ensure the aerosol is thoroughly
shaken to disperse all settled white pigment – agitator balls are present in the aerosol to aid
dispersion).
Ardrox 8901W should be applied in order to produce a thin even coating over the surface
being inspected. The coating will dry almost immediately and the appropriate magnetizing
mode can be used to produce the requisite amount of magnetic flux in the component.
When using current flow or “prod” techniques, ensure that the contact area is not coated
with Ardrox 8901W since it will act as an electrical insulator. If necessary, clean those areas
with Ardrox 5319 prior to magnetization.
Coatings of Ardrox 8901W are not affected by the grades of kerosene commonly used as
carriers for magnetic inks.
The equipment required to produce magnetic flux in the component can vary from small,
hand held units to large, purpose built lathe type benches. SureChem Industries supply a
complete range of Ardrox magnetizing equipment and we would be pleased to offer advice
on the most suitable unit for any component.
When the inspection has been completed, Ardrox 8901W may be removed using Ardrox
5319.
Note: The surface roughness will affect the ease of removal.
EFFECTS ON MATERIALS
When Ardrox 8901W is used in the prescribed manner no significant corrosion is likely to
be encountered on any ferromagnetic materials. The product will degrade the majority
of plastics and rubbers. Intending users are advised to check the compatibility of Ardrox
8901W with any non metallic materials that the product may come in contact with, before
use.
PRECAUTIONS
Avoid contact with skin, eyes and clothing .
In case of eye contact, irrigate thoroughly with plenty of water and seek medical advice.
In case of skin contact, wash thoroughly with soap and water.
When spraying, use under condition of adequate ventilation (do not inhale spray or vapour).
No smoking or other open flames should be permitted when using this product.

DESCRIPTION
A800/3-51/03310
Ardrox 800/3 is a ready to use high sensitivity black magnetic ink consisting of black iron
oxide with a controlled, fine particle size, mineral oil and suspending agent in a high flash,
low aromatic petroleum distillate.
Ardrox 800/51 is a fluid concentrate consisting of highly sensitive black iron oxide with
controlled, fine particle size, suspending agent and mineral oil. It is readily dispersible in
a suitable petroleum distillate, eg. Ardrox Base Oil SC2 to produce a working ink similar to
Ardrox 800/3. Ardrox 800/51 must be diluted with a solvent conforming to AMS 2641 for
the resulting magnetic ink to comply with AMS 3041C.
Ardrox 800/3 and 800/51 (when suitably diluted) conforms to the requirements of AMS
3041C and are approved by Rolls Royce to MSRR 9976.
Ardrox 800/3 is available in aerosol packs complying with AMS 3043B.
Defence Stock No. for Ardrox 800/3 4940-66-
120-8165 for 5 litre packs
6850-66-114-6534 for aerosol packs.
USES
Ardrox 800/3 and 800/51 (when suitably diluted) are used for revealing surface and near
surface defects in ferro-magnetic materials, eg. mild and low alloy steels.
METHOD OF USE
Heavy deposits of grease, rust, scale and paint should be removed prior to inspection.
The component is then magnetized and the magnetic ink applied either by dipping, flowing
or spraying. The component is inspected for defects in daylight or good artificial light.
Defects will show as a collection of black particles.
In areas where it is difficult to see the black indications, eg. on oxidised or other dark
surfaces, contrast may be greatly improved by applying a coating of Ardrox 8901W
background lacquer prior to application of the magnetic ink.
The working concentration of Ardrox 800/51 is 20 g/litre of concentrate in petroleum
distillate. Ardrox 800/3 is used as supplied without any dilution. Containers of Ardrox 800/3
must be thoroughly shaken before use.
METHOD OF CONTROL
The solids content of the tank should be checked regularly. This is best achieved by running
100ml of the ink into an ASTM D96 centrifuge tube, allowing to settle for 60 minutes and
reading the solids content in ml. If it is below the required volume Ardrox 800/51 should be
added. As a guide, for every 0.1 ml below the required volume add 5g of Ardrox 800/51 per
5 litres of ink. The material should then be thoroughly dispersed into the bath.
EFFECT ON MATERIALS
When Ardrox 800/3 and 800/51 are used in the recommended manner no significant
corrosion is likely to be encountered.
Some thermoplastics and certain rubbers may be softened or swollen with prolonged
contact and intending users are advised to check the compatibility of such materials with
the products.
PRECAUTIONS Ardrox 800/3 and 800/51
Avoid contact with skin and eyes. Wear protective clothing including impervious gloves.
In case of skin contact wash thoroughly with soap and water. In case of eye contact irrigate
thoroughly with plenty of water and seek medical advice.
Ardrox 800/3 only: Avoid inhalation of vapour. Ensure adequate ventilation. No smoking,
naked flames or sparks permitted.
Ardrox 800/51 only: The major hazard with Ardrox 800/51 will relate to the petroleum
solvent with which it is diluted. (Obtain health and safety information from the supplier).
