17The OliKrom company has developed the first photoluminescent road paint that lights up at night to make mobility safer
“Phosphorescent stars in children’s bedrooms have been around for a long time!” Said Jean-François Létard, the boss of OliKrom, based in Pessac (Gironde). This former research director at the Bordeaux Condensed Matter Chemistry Institute, a CNRS satellite, has developed a phosphorescent paint that stores light, natural or artificial, and releases it at night.
The technological challenge was to make it resistant to the passage of vehicles, bad weather and the wear and tear of time: “We were able to meet it thanks to an innovation that we obviously keep secret,” continues the manager. Intended in particular for road marking, this paint, which is entering the market, allows a cyclist to see up to 80 meters in front of him at the start of the night, 30 meters at the end – the luminosity decreases as the night progresses, to disappear after ten hours of darkness. Measurements carried out by the French Institute of Transport Sciences and Technologies.
OliKrom, industrial acceleration
Thanks to this innovation, OliKrom (14 employees) hopes to hire between 20 and 30 people within a year and a half. It intends to convince local authorities for their roads, hospitals, retirement homes, schools. And of interest to all those who may be faced with the need to make a place deprived of electricity bright, in order to evacuate it.
“Our paint is obviously more expensive than another one that does not have the same properties. But if we compare it to the price necessary for the installation of lighting in isolated areas, it becomes very cheap“, concludes Jean François Létard. .
