Magnaflux 7HF Oil-Based Visible Magnetic Particle Suspension

Experience the precision of nonfluorescent (visible) wet method magnetic particle testing with this highly-sensitive oil-based magnetic particle suspension aerosol. Designed to provide clear, strong indications, this product is perfect for detecting fine and medium discontinuities in finished parts. Ideal for field testing, spot inspections, and situations where bulk processing is impractical, it enhances inspection capabilities in various environments.

For improved contrast and inspection sensitivity, pair the suspension with WCP-2 white contrast paint, making it an excellent choice for remote inspections of tubing, piping, and large structures.

Maximize indication detection

  • Utilize the smallest particle size available to find indications of all shapes and sizes.
  • Heavy buildup of highly magnetic particles enhances contrast, especially when combined with WCP-2 white contrast paint.
Convenient to use
  • Inspect in all conditions without the need for darkness or UV lights.
  • The aerosol format ensures easy portability for field use.
Wide application versatility
  • Inspect a diverse range of components while avoiding concerns about corrosion or specification non-conformance.
Features
  • Clear indications under visible light
  • Heavy particle buildup for better visibility
  • Excellent particle mobility
  • Corrosion protection for parts and equipment
  • Broad spray pattern for even coverage
  • Superior surface wetting
  • Very low toxicity and low odor

INSTRUCTIONS FOR USE

Use 7HF with appropriate magnetization procedure and equipment. For best results, all components, parts, or areas to be tested should be clean and dry prior to testing to provide an optimal test surface and reduce particle suspension contamination.

1. Use in a well-ventilated area.

2. For best results, apply WCP-2 before 7HF to improve contrast and inspection sensitivity.

3. Shake 7HF aerosol can well before use and occasionally during application to ensure suspension uniformity and concentration.

4. Hold the can 7 to 9 inches (18 to 24 cm) from the area to be tested.

5. Using the continuous or residual application method, spray particle suspension over the test area until it is completely covered.

6. Inspect under visible light. To verify particle concentration, perform a sensitivity check using a known test standard prior to inspection.

REMOVAL

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