Air Cooler Motor

FEATURES • Quickly dissolves grease, oil, lubricants, tar and adhesives. • Effective wash-away of contaminants and colored penetrant. • Fast evaporation to minimize downtime. • Leaves no residue. • Stable, non-staining and non-corrosive. • Safe on most plastics, coatings and rubbers (test prior to use). • Aerosol is equipped with an ‘accusol’ for added convenience. • Pressurized with non-flammable CO2 propellant, giving an active product content of over 97%. • Halogen content tested according to ASME Section V, art 6. 

APPLICATIONS 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. 

. DIRECTIONS 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 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.
