Description
According to our customer's requirement, we can make special luminous powder for water-soluble coatings ---waterproof glow in the dark powder

Photoluminescent pigment:
 
High light and duration 
More than ten years life 
 Non-toxic and harmless
Yellow-green, blue-green, sky-blue voilet etc. avaiable
Aluminate rare earth luminescent powder



Our long-after glow photo-luminescent pigment is strontium aluminate based luminous powder can Emits light by absorption of various visible lights and can be repeatedly used. The products do not contain any radiating elements and can be evenly spread as an additive among the transparent agents such as coating, ink, paint, plastics, cereal, glass, fiber to activate the emitting functions of the agents.
The pigment of the type takes on its natural color in bright places and emits different colors of lights in darkness. It can be used for emergent lighting, indication marks and embellishment.
 
Chemical form: SrMgAl4O8:Eu2+Dy3+
Characteristics:  
1. The photo-luminescent pigment has features of high light and duration.(For example: DIN67510 can glow for 10000 minutes).
2. It can endure light without aging and with chemical stability(it can be used for more than ten years)
3. It is non-toxic and irradiation free; and it is non-inflammable and non-explosive. So it is a new type of luminous material with environmental protection.
4. The photo-luminescent pigment is easy to use and can be used widely.
5. Plenty of glowing color: yellow-green, blue-green, sky-blue, violet, and also pure yellow, red and white etc.
6. Compared with traditional photo-luminescent pigment, by using the chart(table), we can see that the luminosity of our company's photo-luminescent pigment made from rare earth is much greater than sulfide luminescent powder.
