[Midi Libre] Millau experiments with road paint that glows in the dark

Installations marked with photoluminescent paint require no special maintenance or servicing. Only standard road maintenance is required.

What's more, this type of marking is totally autonomous, requiring no charge or power source. So it's an economical and sustainable solution.

The paint itself emits for a very long time. The most important parameter to take into account is the length of time its light emission is perceptible to the human eye.

In an outdoor environment devoid of any light, we consider that the eye can perceive light emission up to around 8 millicandela/m², i.e. after 10 hours of emission. If the environment presents light pollution (full moon, proximity of public lighting), this threshold will be raised and the duration of visibility will be shortened.

Indoors, in absolute darkness, the perception threshold is much lower, and you can observe the luminescence of our paint for over 12 hours.

Our LuminoKrom® paint range can be applied to a variety of substrates and materials. We offer different references to suit every circumstance, whether for indoor or outdoor marking, for example.

Our road and urban paint references are ideal for use on concrete, cement, bitumen and asphalt mixes. A waterborne version is also available for interior applications.Concernant les applications sur du métal, il faudra choisir notre peinture LuminoKrom® pour Métal.

Our luminescent paint is applied over a white primer, so you can apply LuminoKrom® to any surface where the white paint will adhere.
