CircleSafe® 850A is an aerosol spray can of Mi-Glow® 600 red particles and liquid Wetting Agent 771, formulated in water media. It is designed to be used with visible light inspection for detecting discontinuities found in structural fabrications and weldments. Higher particle concentration provides heavier indication buildup for easy detection. CircleSafe® 850A can be further enhanced when used with a UV-A light or blue light. This aerosol is packaged in a carbon dioxide propellant for odor-free, fume-free, non-combustible inspection.
