Last week, Nissan, the renowned Japanese automaker, unveiled its pioneering paint technology designed to enhance vehicle heat management while contributing to a positive environmental impact.
The paint was developed in partnership with Radi-Cool, a leader in radiative cooling solutions.
To create this paint, Nissan used compounds from a metamaterial with unique electromagnetic properties. This product acts as a shield against the sun’s rays, preventing the vehicle from heating up. The technology reflects and redirects the rays away from the car.
In one of the tests conducted, the automaker selected two models—one with the Radi-Cool paint and the other with a standard paint. The vehicle with the new technology showed an external temperature 12°C lower, while the interior was 5°C cooler compared to the other vehicle.
Nissan began considering this technology in 2021, with the goal of implementing more sustainable practices within the company. These efforts aim to combat climate change, reduce emissions, and potentially decarbonize their models.
In total, the company tested around 100 samples of the paint and doesn’t plan to stop there—the goal is to reach 120 microns, roughly six times thinner than the standard.
