“Nissan Tests Heat-Reducing Cabin Paint Technology”

Nissan Motor Co. has been testing this paint on cars driving around Tokyo’s Haneda airport, an area with little shade, making it ideal for evaluating the technology. To the naked eye, the cars painted with the cooling paint look like regular vehicles, but to the touch, they are significantly cooler.

According to the manufacturer, the cooling paint reduces the roof temperature by 12 degrees Celsius (22 degrees Fahrenheit) and the cabin temperature by 5 degrees Celsius (9 degrees Fahrenheit). If applied to electric vehicles, this paint could be advantageous as it would reduce the need for air conditioning, resulting in energy savings.

Cooling materials have been widely used in the construction industry and some other sectors. Nissan’s challenge was to find a way to spray this paint on a large scale and then coat it with a glossy topcoat, similar to conventional car paint.

Toyota Motor Corp. has also experimented with paint that reduces cabin temperature, focusing on colors that refract sunlight.

Nissan’s cooling paint reflects sunlight better and also creates electromagnetic waves that block the sun’s rays, diverting energy away from the car.

Nissan developed this new paint in collaboration with Radi-Cool, a Chinese company. Radi-Cool has created a film, fabric, and coating that can reduce heat. They partner with various Japanese companies, providing hats and parasols that feel cooler. Nissan is the only Japanese car manufacturer working with Radi-Cool.

Susumu Miura, Director of Nissan’s Research Center, stated that there are no significant negative health impacts from the electromagnetic waves emitted by the paint. He mentioned that such waves are all around us.

“My dream is to create cooler cars without using energy,” said Susumu Miura.
