Introduction

MH series photoluminescent pigments are made from alkaline earth aluminate, which is developed and manfactured by MINHUI since 2003. It is non-radioactive, non-toxic,very weatherproof, very chemically stable 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 series has four subcategories according to luminous color: MHG yellow-green, MHB blue-green, MHSB sky-blue, MHP purple. Each category has different models sorted by luminance level and particle size. MHG Yellow-green photoluminescent pigment's chemical formula is SrAl₂O₄:Eu+2,Dy+3. It has a daylight color of light yellow and a luminance color of yellow green.

We also provide MHG in waterproof version. For strontium aluminate pigment's other colors(red, yellow, green, blue, orange, pink, etc.), please see MT series.

MH 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.

Exicitation Emission Spectrum For MHG Pigment

Application

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.
