Mi-Glow(R) 778 is Mi-Glow(R) 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.
