Metal coatings, including coil coatings and automotive coatings, are not just for aesthetics—they must deliver durable color, process stability, and thermal management. Near-infrared (NIR) reflection has become a crucial performance factor for metal panels exposed to sunlight, reducing heat absorption and surface temperature.
IR-1000 is a functional TiO₂ designed to reflect infrared light while keeping the visible color consistent. It allows formulators to create cool colored metal coatings without compromising color appearance, process efficiency, or outdoor durability.
Why Infrared Reflection Matters
Solar radiation consists of UV, visible light, and NIR. While UV can cause degradation and visible light determines perceived color, NIR contributes heavily to heat accumulation. A metal coating with higher NIR reflectance can stay cooler under the same sunlight, improving building comfort, automotive surface performance, and industrial panel heat management.
IR-1000 in Colored Metal Coatings
IR-1000 works in various color systems, supporting L* values from 20 to 96, and can be processed in standard coating operations. It improves NIR reflection while maintaining color, dispersion, durability, and cost-effectiveness.
Yellow Metal Coating (RAL 1005 Honey Yellow)
IR-1000 formulation: L* 47.67, a* 0.48, b* 0.63, TSR 0.48, NIR 0.63
Pigmentary TiO₂ formulation: L* 47.28, a* 15.50, b* 68.78, TSR 0.44, NIR 0.54
IR-1000 increases NIR reflectance without changing the yellow hue, making it ideal for industrial panels, transportation coatings, and decorative metal surfaces.
Blue Metal Coating (RAL 5005 Signal Blue)
IR-1000 formulation: L* 50.38, a* -17.09, b* -36.20, TSR 0.43, NIR 0.72
Pigmentary TiO₂ formulation: L* 50.91, a* -17.49, b* -36.10, TSR 0.38, NIR 0.63
Blue coatings gain significant NIR improvement, reducing solar heat buildup while keeping visible color stable, important for roofing, automotive panels, and industrial metal applications.
Green Metal Coating (RAL 6029 Mint Green)
IR-1000 formulation: L* 60.61, a* -50.18, b* 19.35, TSR 0.39, NIR 0.65
Pigmentary TiO₂ formulation: L* 61.46, a* -48.86, b* 19.60, TSR 0.33, NIR 0.51
Green coatings see a clear NIR boost, helping architectural façades and industrial panels remain cooler while preserving vivid color.
Red Metal Coating (RAL 8004 Copper Red)
IR-1000 formulation: L* 48.49, a* 52.20, b* 23.67, TSR 0.53, NIR 0.76
Pigmentary TiO₂ formulation: L* 49.25, a* 52.79, b* 24.16, TSR 0.50, NIR 0.71
Red coatings benefit the most in NIR reflectance, making them suitable for automotive, decorative, and branded metal surfaces where heat reflection is critical.
IR-1000 allows metal coating formulators to combine color design, heat reflection, and long-term durability. Each color system—yellow, blue, green, and red—shows NIR improvement while keeping the visible appearance stable. This functional TiO₂ supports next-generation cool colored metal coatings for coil, automotive, and industrial applications.
