An eco-sustainable solution

For better safety on the roads

Poor visibility at night is one of the biggest challenges on roads, and it can lead to hazardous situations. However, adding long-afterglow light-emitting phosphorescent materials to traffic white paint can be a solution to this problem.

Afterglow luminous powders can absorb sunlight or ambient light throughout the day and release it as colored light during the night, which makes them an advanced technology compared to other solutions.

Benefits of EverBrightGreen®

Enhanced Night Visibility

The phosphorescent paint emits light, allowing for excellent visibility even in the absence of streetlights or low-light conditions.

Long Duration of Glow

The duration of the night glow can be adjusted to 12 hours, providing continuous visibility throughout the night.

Optimum Color Selection

The available colors are deep blue, blue-green, and green. Green or bluish-green hues are the optimal colors as they are most sensitive to the human eye, maximizing visibility for drivers.

Rain and Wet Surface Resistant

The phosphorescent material can be protected with a plastic medium, such as poly-methyl-methacrylate (PMMA), ensuring durability and performance in wet conditions.

Application and Considerations

To achieve the best visibility at night, a paint-to-material ratio of 1:0.3 is recommended, optimizing the light output. Methyl methacrylate-based road paint with EverBrightGreen® materials is an ideal choice for this technology. It provides the necessary protection, longevity, and adhesion to road surfaces.

Visibility evaluation findings

  • Under normal weather conditions, brightness
    was increased by 4 mcd/m2.
  • Under foggy weather, brightness was
    increased by 4 mcd/m2.
  • Under rainfall conditions (30 mm/h), brightness
    increased over 13 mcd/m2.
  • In the absence of a streetlight and a headlight,
    the white line was completely invisible while
    the new road marking was still visible with a
    brightness of about 0.6 mcd/m2.
  • The proposed new road markings meet the
    minimum requirements of the human eye
    detection of 0.32 mcd/m2 under adverse weather
    conditions.

Durability and sliding resistance

  • Wear resistance depends on particle size and sample concentration.
  • The larger the particle size, the better the durability.
  • The optimal particle size is 50–250 microns.
  • Sample loading concentration in the range of 15–50%
