Nissan has introduced a new „cool paint“ technology specifically designed for vehicles, aiming to reduce interior temperatures and decrease the need for air conditioning. This innovative approach to thermal coatings presents unique features and benefits that set it apart from traditional thermal paints commonly used in commercial buildings.
One of the key features of Nissan’s cool paint is its advanced microstructure. The paint contains two types of microstructure particles that work together to reflect solar energy and reduce heat absorption. One type of particle reflects near-infrared rays, which are responsible for generating heat in traditional paints. The other type creates electromagnetic fields that redirect solar energy back into the atmosphere, further reducing heat buildup on the vehicle’s surface.
In terms of application and durability, Nissan’s cool paint is applied in a thin layer of 120 microns, significantly thinner than typical thermal paints used in commercial buildings. This thin layer allows the paint to be sprayed onto vehicles, maintaining the ability to apply a clear top coat for protection against scratches and road damage. This thin application also helps to keep the overall weight of the vehicle down, which is crucial for maintaining fuel efficiency and performance.
While the cool paint technology offers significant benefits in terms of reducing interior temperatures and energy consumption, there are some considerations to keep in mind. The cost of the cool paint is expected to be higher than traditional paints, which may impact its accessibility to consumers. Additionally, although thinner than most thermal paints, the cool paint is still thicker than standard car paint, potentially adding weight to the vehicle. Nissan is actively exploring various thicknesses and colors to optimize the paint for road use and minimize any negative impacts on vehicle performance.
Looking towards the future, Dr. Susumu Miura from Nissan’s Advanced Materials and Processing Laboratory highlights the importance of reducing energy consumption for cooling, particularly in the era of electric vehicles. The cool paint technology has the potential to lower air conditioning use, extending the range of electric vehicles and enhancing overall vehicle efficiency. Nissan’s ongoing tests and development efforts are focused on making this innovative technology widely available for road cars, further solidifying the company’s position as a leader in thermal coatings for automotive use.
In conclusion, Nissan’s cool paint technology represents a significant advancement in thermal coatings for vehicles, offering unique features and benefits that address the challenges of keeping interiors cool while maintaining a light, thin, and durable finish. With a focus on reducing energy consumption and enhancing vehicle efficiency, Nissan’s innovative approach to thermal coatings sets it apart in the industry and paves the way for a more sustainable and comfortable driving experience.
