Mi-Glow® 778 Fluorescent Concentrate for use in Water Bath

General Description:

Mi-Glow® 778 is Mi-Glow® 800 fluorescent yellow-green particles premixed with liquid Wetting Agent 771 for use in water media

This advanced formulation allows for superior corrosion protection, wetting and particle mobility. It is designed to be used with UV-A light to detect very fine discontinuities in finished products. This material is used in the automotive and aerospace industries on finished component parts, where extra corrosion protection is required.

Physical Characteristics: Forest green powder with a slight detergent odor.

Typical Properties: (Not a specification)


  Mi-Glow® 778
Particle Color Fluorescent Yellow/Green
Average Particle Size 5 µm
AMS Standard 3044
SAE Sensitivity* 8
Temperature Range 32-120°F (0-49°C)
*Representative of the number of lines shown on an AISI 01 Ketos tool steel ring as defined in SAE AS5282

Preparation: The change-over from a solvent system to a Mi-Glow® 778 system requires a thorough cleaning of the tank and piping. This can be accomplished in most cases by flushing the system twice, using about 1/2 gallon of Cleaner 500 and 10-15 gallons of water. Flushing should be followed by a water rinse.

Mi-Glow® 778 should be used at a dilution of 1 part concentrate with 39 parts of water. This will give a fluorescent particle concentration of 1.3 grams per liter. The recommended proportion may vary depending on specific applications. Each bottle should be thoroughly mixed before using. If a bottle is emptied, it should be rinsed with water and the contents added to the system.

Specification Compliance: Particles meet all relevant industry specifications, including but not limited to ASTM E 1444, AMS 3044, MIL-STD-271, NAVSEA 250-1500-1, NTR-1E.

Shelf Life: One (1) year, when sealed bottles are not subjected to extreme heat or cold.
