Although still in the testing phase, initial results indicate a substantial reduction in both surface and interior temperatures for vehicles
If you think cars are already overloaded with technology, wait until you see this. Nissan is developing a new type of exterior automotive paint that utilizes electromagnetic waves to keep both the surface and interior cooler. Although it’s still in the testing phase, the early results are very promising.
Nissan is collaborating with Radi-Cool, a company that specializes in cooling products. While the concept of radiative paint isn’t new—it’s been used on buildings for years to keep indoor spaces cooler—these applications typically use a very thick paint that lacks the durability and shine of an automotive finish and is applied with a roller. Although people have painted cars with rollers, it’s not the ideal method for achieving a high-quality color finish.
This new formula is intended for use with spray guns and is compatible with clear topcoats. Despite being designed for spray application, it remains quite thick—six times thicker than a typical automotive finish. The paint contains two microstructure components that enhance its cooling properties. The first component reflects near-infrared rays, a common method for reducing heat. The second component introduces the scientific innovation: it generates electromagnetic waves that not only absorb sunlight but actively counteract it, helping to prevent heat transfer to other parts of the car.
Dr. Susumu Miura, the senior manager of this project, explained, “My goal is to develop cars that stay cooler without using additional energy. This is particularly crucial in the era of electric vehicles, where the energy required to operate air conditioning during summer can significantly affect the battery charge.”
Nissan hasn’t detailed the specifics of the paint or how the electromagnetic waves are generated, but the results are compelling. Comparisons show a temperature reduction of 12 degrees Celsius on the exterior of cars with this special finish, and the interior also cooled by 5 degrees Celsius.
As for when you might be able to order a new Z or Rogue with this “cool” paint, development is still underway. Nissan aims to make the paint thinner for easier application. If it reaches production, it will likely be available only for special-order vehicles.
