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.
