Recent advances in pigmentation technology have allowed formulators to achieve a greater infrared reflectivity versus traditional pigmentation technologies in functional coatings, while maintaining the appropriate light absorption in the visible spectrum to impart color. The ability of functional infrared reflective coating systems to lower heat build-up results in reduced thermal warpage, reduced thermal cycling degradation, lower energy costs related to cooling, and improved comfort and functionality of dark color exterior objects such as park benches, hand railings, and even polymer concrete. This paper will impart knowledge of infrared pigmentation technology to the reader, and explore potential new applications of infrared reflective pigmentation technology in composites.
