Lumor J (HF) is a fluorescent magnetic particle linker available in aerosol form (approx. 400 ml). The product is used in magnetic particle inspection (MPI) to identify surface and near-surface defects in ferromagnetic materials. Under UV light of approx. 365 nm, the particles light up with a bright yellow-green fluorescence, providing optimal visibility and reliable inspection even under demanding conditions.

Key features and benefits

• High magnetic response provides precise indication of defects.

• Low coercivity ensures uniform particle distribution without clumping.

• Supplied in an aerosol can (400 ml) for easy and effective application.

• Very high flash point for safe and secure use.

• Fluorescence under UV light provides clear contrast and high sensitivity.

Technical specifications

• Formulation: Finely divided fluorescent magnetic particles in a hydrocarbon carrier.

• Inspection with UV light: approximately 365 nm wavelength.

• Particle size: very fine for accurate defect detection.

• Packaging: aerosol 400 ml, also available in larger volumes.

• Shelf life: long life when stored correctly.

Areas of application

• Inspection of welds, castings and forged components.

• Aviation, automotive, petrochemical, shipbuilding and power plants.

• Check for breaks, scratches and cracks that are not visible in normal light.

• Perfect for both workshop and field work with fast and mobile use.
