The article concerns experimental studies on the impact of the paint application method on the light reflectance coefficient in the wavelength range from 180 to 2500 nm, with particular emphasis on the analysis of reflectance in the infrared wavelength range, which affects surface heating. Additionally, studies were conducted on the effect of prior UV light exposure on the light reflectance coefficient. The results show that controlling the application pressure is a key parameter in optimizing the reflectance properties, particularly in the infrared range, which has a direct impact on surface temperature regulation. The findings are significant for improving coating durability and energy management efficiency. This research also highlights the potential for environmentally sustainable applications in the automotive industry and other sectors, by optimizing coating methods to reduce energy consumption and material degradation. Quantitative results from this study indicate that applying paint at pressures ranging from 1 to 5 bar leads to a change in the infrared reflectance coefficient of up to 24%, providing valuable insights into how application methods affect surface properties.
