Solvent cleaner to prepare the surface for examination.

A fast drying cleaner for the removal of all kinds of contaminants on the surface to be inspected. Serves as a preparation of the surface before inspection with liquid penetrant



Quick drying solvent cleaner/degreaser and excess penetrant remover for the non- destructive testing of metal surfaces by liquid penetrant inspection.

Many cracks in engineering materials can be deep in spite of having a very small opening width on the surface and can cause very serious defects. By normal visual inspection such cracks may be very difficult to detect, but penetrant flaw detection is an extension of the visual inspection method. The control is carried out using 3 products: Crick 110 (cleaner), Crick 120 (penetrant) and Crick 130 (developer).

Crick 110 is a fast drying, powerful degreasing solvent blend free of 1,1,1-trichloroethane or other chlorinated solvents for the removal of dirt, grime and contaminants. Designed for the pre-treatment of the surface, prior to liquid penetrant inspection and to remove all visible, colored traces of the penetrant.

Non-destructive inspection of materials, parts, assemblies, equipment, surfaces or structures:

  • Cracks, lack of fusion and open cavities in welded
  • Cracks and cavities caused by metal fatigue and cutting
  • Check of porosity or leaks in pipes, tanks, boilers, heat
  • Discontinuities, laps, folds and cracks in castings, forgings and

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


  • Cleaning of the surface

The surface to be checked must be clean, degreased and dry. All soiling 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, colored 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. If necessary, post-clean the controlled surface and protect against corrosion with one of CRC’s corrosion protection products.

A safety data sheet (MSDS) according EU-directive 93/112 is available for all CRC products.
