Product Information

Chemetall Ardrox 8903W White Contrast Paint

Chemetall Ardrox 8903W is a quick drying white paint which is designed specifically for the use in the colour contrast method of magnetic particle inspection. It provides a dense white background against which black or red indications of defects can be seen readily.

Ardrox 8903W is ideal for use with either oil based or water based magnetic inks.

Ardrox 8903W is available as aerosol cans or bulk material. It offers optimal performances when used together with the colour contrast magnetic inks Ardrox 800/3.

Benefits

Maximize indication detection

  • See indications more easily with the white paint, opaque surface which highlights indications while minimizing glare/reflections

Increase inspection speed

  • Speed up inspections by applying a clean coat on the first pass
  • Dries quickly to create an optimal surface for faster indication formation

Application versatility

  • Comes in a convenient aerosol to take it with you wherever you go
  • Can be used with wet or dry method magnetic particles on virtually any part
  • Conforms to ISO 9934-2 and OMAT 264 (approval) specifications

Instructions for use

Ardrox 8903W can be applied to the area to be inspected by spraying or brushing. Application by aerosol is by far the most common method as it is much easier to obtain a dense even film. Aerosols are also convenient to use, particularly for in-situ inspection. There can be more wastage of product with brush application due to the volatility of Ardrox 8903W.

It is essential that aerosols are shaken before use and, for brushing applications; containers must also be shaken thoroughly. Surface temperature should be between 0 and 50°C (30-120°F). Ardrox 8903W is applied to dark coloured ferromagnetic surfaces and allowed to dry before applying the magnetic particles.

This ensures a good colour contrast between the white paint and the red or black particles making it much easier for the inspector to identify and interpret the indications. Ardrox 8903W is used extensively in conjunction with Ardrox 8032 ink in aerosols particularly for the in-situ inspection of welded fabrications or structures, pressure vessels and pipelines.

Removal

Ardrox 8903W can then be left on the surface or removed with the appropriate Ardrox solvent cleaner.

All components, parts, or inspection areas must be properly demagnetised before cleaning to ensure easy particle removal. Cleaned parts may be treated with a temporary film protective coating if longer corrosion protection is required.

Storage

Store in a well-ventilated area away from magnetising equipment and heat sources. Product age, exposure to elevated temperatures, and / or exposure to a strong magnetic field may adversely affect particle distribution. Please refer to safety data sheet for additional instructions.
