  • Product Detail



    MH-W series is a series of wateproof photoluminescent pigment, which is manufactured with MH pigments(strontium aluminate doped with rare earth) 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. 

    MH-W series is non-radioactive, non-toxic,very weatherproof and with a long shelf life of 15 years. Compared to traditional glow in the dark pigment(zinc sulfide based), MINHUI's pigment can glow 10 times longer in the dark and 10 times brighter. After absorbing various visible light or ultroviolet light for 10-30 minutes, it can glow for more than 12 hours in the dark continously. Its light absorption and emission ability can be used indefintely and minimizes the emission of greenhouse gas, making our pigment the most environmental friendly and durable light sources. 

    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.

    This serie's photoluminescent pigment meets the US requirement of ASTM F963-16 (Standard Consumer Safety Specification on Toy Safety), Test Method CPSC-CH-E1003-09.1 for total Lead, and  ASTM F 963-16 (Clause 8.3) for soluable heavy metal; and registered for EU REACH standard in accordance with the REACH regulation (EC) No 1907/2006.

    We now owns 5 production lines of photoluminescent pigment and has the annual capacity to manufacture 500 tons of pigment. Our R&D team can also help you to develop a unique type of pigment that fully suits your application, with customized luminance level, glow length, grain size and color. We have 20 years experience of exporting and our photoluminescent matierals and products are loved by customers from all over the globe.



    Photoluminecent pigment can be mixed with resin, epoxy, paint, plastic, glass, ink, nail polish, rubber, silicone, glue, powder coating and ceramics to make their glow in the dark version. It has been widely applied to fire-fighting safety signs, fishing tool, craftworks, watches, textiles, toys and gifts, and so on.
