Penetrating colorant to mark the cracks and failures.
Red colored, water washable penetrant for non-destructive testing of metal surfaces. The penetrant can flow into tiny cracks within a time frame of 10 to 20 minutes. The excess of penetrant has to be washed away before using the developer.
Features
- The check can be carried out with ready-to-use aerosols.
- It produces results in a speedy and easy way.
- An economical technology with no need for expensive and advanced equipment.
- A sensitive and reliable test method.
- Widely applicable, regardless the nature of the materials and shape of the objects.
- The aerosol uses a hydrocarbon propellant for controlled application.
- Halogen content tested according to ASME Section V, art 6.
Product Used
Non-destructive inspection of materials, parts, assemblies, equipment, surfaces or
structures:
• Cracks, lack of fusion and open cavities in welded parts.
• Cracks and cavities caused by metal fatigue and cutting operations.
• Check of porosity or leaks in pipes, tanks, boilers, heat exchangers.
• Discontinuities, laps, folds and cracks in castings, forgings and ceramics.
Direction to Used
Do not use at ambient temperatures below 10°C.
• In liquid penetrant inspections, the test object or material is coated with a visible dye
solution. The excess dye is removed from the surface and a developer is then applied. The
developer acts like a blotter and draws penetrant out of the imperfections of the surface.
With visible dyes, the vivid color contrast between the penetrant and the developer makes
the ‘bleed-out’ easy to see.
• Cleaning of the surface
The surface to be checked must be clean, degreased and dry. All soil, like rust, oil, grease,
paint etc, which can mask the imperfections, must be removed. Finish the cleaning by
spraying CRC Crick 110 generously. If possible wipe with an absorbent cloth and allow
drying thoroughly.
Penetrant application
Shake the can of CRC Crick 120 prior to use. Spray the penetrant in a light, even film on
the surface, wetting all areas to be controlled. Allow to drain for 10 to 20 minutes.
• Excess penetrant removal
Remove excess of penetrant by wiping the surface using a lint-free cloth. Apply water
(CRC Crick 120 is water washable) until all visible, coloured traces are removed. Care
must be taken that only disturbing penetrant on the surface is removed. Dry properly.
• Development
Shake the can of CRC Crick 130 thoroughly prior to use. Spray a light, homogeneous coat
of developer from a distance of about 20 cm. Avoid any excess developer to avoid
masking the finest flaws. Allow to develop for at least 7 minutes so that imperfections are
visible.
• Visual inspection of defects
As time passes, the defects will appear as red spots or lines on a white background. The
speed of appearance, the shape and dimensions can give information about the nature of
the defects. Post-clean the controlled surface and protect against corrosion with one of
CRC’s corrosion protection products.
A safety data sheet (MSDS) according to EC Regulation N° 1907/2006 Art.31 and
amendments is available for all CRC products.
