Product Data Sheet – MAGNAGLO MG-MX Carrier II

Oil-based Carrier Fluid

MAGNAGLO® MG-MX Carrier II is an oil-based carrier fluid for the suspension of wet method magnetic particles .It provides excellent particle mobility, good suspension stability and enhanced corrosion protection. Carrier II has virtually no odour and contains special additives to minimise background fluorescence when using fluorescent materials.

Benefits

Facilitates fast, reliable inspection

  • Increases inspection speed and reliability by quickly wetting the entire test surface.

Minimises maintenance

  • Magnetic particle baths last longer due to slow evaporation, and are less susceptible to contamination from bacteria or fungus.
  • Protects magnetic particles like 14A from wear-and-tear, and keeps them evenly dispersed throughout the bath.

Improves operator comfort

  • Made with a highly refined oil to reduce skin irritations.
  • Low odour for a nicer work environment.

More inspection flexibility

  •  Can be used for virtually all magnetic particle inspections.
  • Conforms to all major international magnetic particle testing specifications.
  • Prevents corrosion of most alloys and eliminates post-inspection processing for corrosion protection.

Safer to use

  • Reduces Health & Safety concerns with its high flash point and low toxicity.
  • Suitable for use anywhere without worrying about fire or biological hazards.

Increases equipment life-span

  • Protects magnetic particle equipment from internal rust and corrosion, to help keep expensive machines running longer with less downtime.

Case Study

Instructions for Use

Clean the component before testing to ensure a suitable test surface and prolong bath life.

Add your magnetic powder to MG-MX Carrier II at the required concentration and mix thoroughly. Check the ink strength before use.

You will need to continually agitate the ink during testing to ensure an even suspension of particles.

During use, the magnetic content of any ink will become depleted so you will need to check it at least once a day. The most widely-used way of checking an ink’s settlement volume is by using a graduated ASTM pear-shaped centrifuge tube.

When the settlement volume approaches the lower limit, you can add more powder/concentrate to the bath as long as it is still clean and uncontaminated. If the bath looks contaminated, or if it has been in use for a long time, replace the contents.

After inspection, remember to completely de-magnetise your components before cleaning, to ensure easy removal of any residual powder particles.
