Ardrox 996PB Red Dye Penetrant
The ARDROX 996PB aerosol process provides an effective, portable method of flaw detection. It consists of ARDROX 996PA red dye penetrant, ARDROX 9D1B developer and 9PR5 solvent penetrant remover.
The ARDROX 996PB Flaw Detection Process is used as a local inspection method to find cracks, porosity and similar surface discontinuities in all types of metals, certain ceramics and plastics. It has wide uses in the general engineering and aerospace industries, particularly where large structures are encountered, or where immersion methods would be uneconomical or impossible.
ARDROX 996PB contains low levels of sulphur, halogen and alkali metals. Batch certification is available on request.
- ARDROX 996PA red dye penetrant
- ARDROX 9D1B developer
- ARDROX 9PR5 penetrant remover
Method of use
The process consists of the following stages:
- Ensure that the surface to be inspected is free from rust, scale, carbon, paint, oil or grease. Clean area to be inspected with ARDROX penetrant remover.
- Apply ARDROX 996PB to the area to be inspected and allow the penetrant to remain on the surface for 10 – 30 minutes. Remove as much as possible of the excess penetrant by wiping with a clean cloth or tissue. Remove the remaining excess penetrant with a cloth or tissue, moistened with ARDROX 9PR5 penetrant remover. Do not spray the penetrant remover directly onto the penetrant.
- Spray a thin even film of ARDROX 9D1B onto the surface.
- Inspect for coarse defects immediately and leave for at least 10 minutes before inspecting for fine defects. Inspection should be carried out in daylight or good artificial light. Cracks, fold or cold shuts are revealed as red lines and porosity as a series of dots.
Effects on materials.
When the ARDROX 996PB process is used in the prescribed manner, no significant corrosion is likely to occur. They may, however, have a softening or swelling effect on certain plastics and rubbers. Intending users are recommended to check their requirements in this respect.
