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

Paint parked in the sun external surface temperatures in vehiclesAlthough the temperature was reduced by 12°C, the internal temperature was also reduced 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 lower the outside surface temperature?

Nissan Research Center Advanced Materials and Processing Laboratory Dr. Susumu Miura and his team continue to work on making automotive paint thinner and more commercially viable. The paint is currently six times thicker than typical automotive paint, which poses a significant barrier to its transition to commercial use. However, Miura believes that this new technology will one day be available for special orders, especially in a variety of colors commercial vehicles that are driven outside for extended 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 solar reflectance of 97.9% in 2022. Other automakers, such as Toyota, are also working on passively cooling exterior paints. These innovative approaches car industryIt shows that important steps have been taken in the field of energy efficiency and sustainability in Turkey.
