  • Product Detail


    MH-W series is a series of waterproof strontium aluminate based or calcium aluminate based photoluminescent pigment. It is manufactured with MH pigments through coating process. It has the same performance regarding luminance level, color and grain size as MH series. This series's pigment be directly used for water-based paint or ink. We also recommend using it for photoluminescent products that have to be immersed in water for a long peiod of time, for example in outdoors. 

    MH-W series is non-radioactive, non-toxic,very weatherproof and with a long shelf life of 15 years. After absorbing various visible light or ultroviolet light for 10-30 minutes, it can glow for more than 12 hours in the dark continously. 



    MH-W series photoluminescent pigment has four categories according to luminous color: MHG-W yellow-green, MHB-W blue-green, MHSB-W sky-blue, MHP-W purple. Each category have models with different luminance quality and particle size.
