Product details:

Photoluminescent pigment powders (luminous powder, long afterglow fluorescent powder) are light energy storage powders which can glow in the dark after absorbing various visible light under 450 nm and can be reused for many times. These products 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 photoluminescent pigments can glow different colors in the dark, and works with good performance for low-location emergency lighting, indication marks and decorations. The photoluminescent pigment powders are widely used in the fields of consumer goods, decorations, communication and transportation , military facilities, and fire emergency system etc. 

Colorful photoluminescent pigment is a mixture of alkaline earth aluminate photoluminescent pigment (or alkaline earth silico-aluminate photoluminescent pigment) and organic fluorescent pigment. These photoluminescent pigment powder products combine the advantages of light-storing photoluminescent pigment and rich in color of fluorescent pigment. They exhibit a tunable body color and glowing color to meet the wide range of application requirements.
