Product Introduction: The ST-RT421 Aerogel Reflective Thermal Insulation Coating features spectral selectivity and exceptional solar thermal reflection properties. Utilizing aerogel and nano-composites with spectral additives and composite cooling powders, this coating achieves over 70% reflectivity while radiating absorbed thermal energy into the surrounding environment through infrared wavelengths. As a versatile solution compatible with nearly all substrates, it stands as the industry-standard choice for thermal reflection, insulation, and radiation control. During summer when prolonged direct sunlight causes substrate temperatures to exceed 50°C, this coating provides optimal thermal protection.
