Product details:

Photoluminescent pigment (luminous powder, long afterglow fluorescent powder)is a kind of light energy storage powder which can glow in the dark after absorbing various visible light under 450 nm and can be reused for many times. The product can be mixed as additive with the transparent media as coating, printing ink, paint, plastics, printing paste, ceramics, glassware and fiber to enable the media to glow in the dark. The pigment can glow different colors in the dark, and works with good performance for low-location emergency lighting, indication marks and decorations. The pigment is widely used in the fields of consumer goods, decorations, communication and transportation , military facilities, and fire emergency system etc. 

The features of sulfide photoluminescent pigment are fast light absorption, bright body color and glowing color. The product should be preserved in well closed containers and protected from light due to the deliquescence in air and decomposition under ultraviolet light.

    ⑴The unit of particle size is μm. The particle size is expressed by Medium Particle size (D50).
    ⑵The unit of afterglow brightness is mcd/m2. All the tests are executed according to the standard of DIN67510, which is to detect afterglow brightness of the sample for 1 min excited by D65 standard light source illumination of 1000LX for 5 min.
