FAQ
Cool pigments are engineered to absorb visible light (appearing grey/dark) but reflect near-infrared radiation (700–2500 nm) that carries ~50% of solar energy. By reflecting NIR, the coating surface absorbs less total solar energy, reducing substrate temperature by 10–30°C compared to conventional dark coatings.
