Cool Paint from Nissan to Prevent Vehicles from Heating

Nissan, developed an innovative automotive paint that can reduce outdoor temperatures by up to 12°C. The new paint resists sunlight and reflects infrared rays, keeping vehicles cooler. Although the dye is currently far from being commercially viable, it is intended to be available for mass production in the near future. Nissan actually started testing the cold paint on Nissan NV100 service vehicles at Tokyo International Air Terminal in November 2023.

Paint parked in the sun exterior surface temperatures in vehiclesWhile it reduced the temperature by 12°C, it also reduced the internal temperatures by 5°C. This cooling effect was possible because the metamaterials used in the paint reflect near-infrared rays and create electromagnetic waves in response to sunlight.

Does Paint Reduce Exterior Surface Temperatures?

Dr. from Nissan Research Center Advanced Materials and Processing Laboratory. Susumu Miura and his team continue to work to make automotive paint thinner and commercially viable. The paint is currently six times thicker than typical automotive paint, presenting a significant barrier to transition to commercial use. However, Miura believes that this new technology may one day be available for special orders in a variety of colors, especially commercial vehicles operating outside for long periods of time He believes it has great potential.

Nissan, this type cooling technologies It’s not the only company working on it. A team from Purdue University developed a white paint with a 97.9% solar reflectance rate in 2022. Other automakers, such as Toyota, are also working on passive cooling exterior paints. These innovative approaches automotive industryIt shows that important steps have been taken for energy efficiency and sustainability in Turkey.
