Wecryl 481 GlowLine

Luminescent Marking

Brief Description

Wecryl 481 GlowLine is a luminescent, thin-layer marking system. Wecryl 481 GlowLine absorbs energy from UV radiation, daylight or artificial light and acts as a light source in the dark, when it releases that energy again. This process can be repeated endlessly. Wecryl 481 GlowLine incorporates highly sophisticated pigments to meet the requirements of DIN 67510 part 1, class C, and can therefore be used to complement existing emergency lighting and escape route marking systems.
