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: Four (4) years, when closed containers are stored in a clean, dry environment away from excessive heat and cold.
