Wet Visible (Black &White) Mag Particle Materials

Wet Visible (Black &White) Mag Particle Materials

Wet Visible Black particles are used with White Contrast Paint for detection of SCC (stress corrosion cracking). Sensitivity approaches that of fluorescent particles. Use this method when it is not practical to darken the inspection site and use a UV lamp with fluorescent particles.

This method is known as Black & White method and is the most widely used technique outside of North America.
