Ready-to-use Visible Magnetic Ink

Chemical product icon - visible magnetic

General Description

BYCOTEST® 103 is an oil-based, ready-to-use black ink that gives clear black indications when viewed in daylight.

Applications

Used in conjunction with suitable magnetising equipment, 103 will locate medium-fine surface and slightly subsurface defects in ferrous materials. Typical defects found include shrink cracks, welding defects, grinding cracks, quenching cracks and fatigue cracks.

Composition

103 consists of a suspension of black magnetic particles in a high-flash, low-odour petroleum distillate.

Benefits

  • Ready to use
  • High sensitivity
  • Clear indications

General Method of Use

Clean the component before testing to reduce the risk of contamination and provide a suitable test surface.

If the test surface is a dark colour, apply a thin coating of a suitable white contrast paint – such as 104A or 104Plus – to provide a better contrasting background.

Shake the aerosol can for 30 – 60 seconds initially to ensure that the ink is mixed thoroughly. You will need to shake the can repeatedly during use.

Spray the ink onto all surfaces of the component. The indications will be formed during the application of a magnetising current.

After inspection, the components should be properly demagnetised before cleaning.
