MI-GLOW 778 is a green liquid concentrate used for magnetic particle inspection in a
water system. It contains fluorescent particles and special water chemistry, which
consists of corrosion inhibitors, anti-foaming agents, wetting agents, and pH buffering
agents. MI-GLOW 778 is designed for revealing very fine defects on both machined and
unfinished ferro-magnetic materials.
Particle Color: Fluorescent yellow-green
Specific Gravity: 1.3 g/ml -- for the concentrate
Particle Size: Not less than 98% passage through U.S. Standard No. 325 mesh sieve (45 μm)

particle size of 5 μm.
Particle Sensitivity: MI-GLOW 778 shows a minimum of 8 lines on an AISI 01 Ketos tool steel
ring (as defined in SAE AS5282), set on a 1-inch diameter copper bar, magnetized with 2500 A of
Particle Certification: Particles meet all relevant specifications, including but not limited to MILSTD-
1949, AMS 3044, MIL-STD-271, NAVSEA 250-1500-1, NTR-1E, ASTM E 1444.
