YECOA YL-808 is high-sensitivity fluorescent magnetic particles, which show yellow green

fluorescent color under Black light (ultraviolet radiation wavelength of 365nm). It is of a non-corrosive,

low toxicity, high-boiling point, oil-based type as an economical and efficient product with certain

identification since it is uniformly coated upon spray with addition of a special dispersant and refined

fluorescent magnetic particles.

● Seams, Shrinkage Cracks, Tears, Laps, Flakes.

● Welding Defect, Grinding Cracks, Quenching Cracks, Fatigue Cracks.

● Iron, nickel, cobalt and their alloys being materials suitable for magnetic particle testing 

    (Magnetic body products)

● Always wear safety equipment before work.

1. Please clean the contaminants on the surface that needs to be tested with cleaner

    (YL-801)(Dry Time 5 ∼10min)

2. Please form the magnetizing current magnetic field.

3. Please spray the fluorescent magnetic particle spray (YL-808) evenly.

4. Please shine the Black Light (Ultraviolet Ray Wavelength 365nm).

5. Please examine the testing area with naked eye.
