Conducted tests according to automotive specifications (Nissan Motor internal standards) to confirm the maintenance of cooling performance.
At Nissan Motor Co., Ltd., we conducted performance verification of "Radi-Cool." In the salt spray test, which assesses paint adhesion, we confirmed that the surface of the painted board was approximately 7°C cooler than conventional painted boards. In the weather resistance test using xenon irradiation, we demonstrated that there were no structural changes or variations in radiative cooling performance. Additionally, we can confirm the maintenance of cooling performance, as the untreated wall side in the logistics warehouse was nearly 30°C, while the treated roof surface was in the low 20s°C. 【Durability Test Details】 ■ Salt Spray Test (Paint Adhesion) ■ Weather Resistance Test (Xenon Irradiation) *For more details, please download the PDF or feel free to contact us.
