Glow in dark photoluminescent pigment for roading marking paint
Product Description
Photoluminescent pigment (Strontium Aluminate glow in dark pigments) is a kind of rare earth photoluminescent powder, with no radioactive component. After absorbing visual light, sunlight, lamp light, UV light etc, it can store the energy and give off light in dark. This process can be repeated for ever.
Features:
Luminescent pigment(Glow in the dark) are self-luminous products made of alkaline earth aluminates or silicates doped with rare earth.
1. Afterglow can be maintained for more than 8 hours after 10-20 mins absorbance of visible light, such as Sunlight;
2. It is harmless, non-toxic non-radioactive elements and can be recycled for unlimited times;
3. It can be easily mixture with all kinds of chemicals with good durability and stability.
4. It has the features of high initial brightness and long afterglow and will provide convenience and security to all industries.
