General description

Photoluminescent pigments are a type of glow-in-the-dark powder which gathers energy from light and emits it to give a glowing effect. The pigment absorbs a wide spectrum of visible light and UV rays and then emits this energy with an after-glow. This process can be repeated many times.

Photoluminescent pigments are not radioactive nor toxic and can be mixed with light-coloured, transparent materials such as other pigments, paints, plastic, printing pastes, ceramics, glass and fibers which allows to achieve glow-in-the-dark effect.

This pigments can radiate different colours and are ideal for the production of LLL systems, evacuation signage and various decorations. They have a wide consumer usage and are applied in various fields such as transport and communication, military buildings, fire safety systems or decorative accessories.
