The goal of this research is to compare our own formulation of near infrared radiation (NIR) pigment coating to commercialized ones. These near infrared coatings are designed to be used on roofs of buildings to keep the buildings from absorbing the heat from the sun’s radiation. This would keep the building cooler and use less energy and money to cool the building. In this study, Styrofoam was used to build a lab-scale house and were put under heat lamps that mimicked the sun. Temperatures were taken at three different locations to determine the effectiveness of the pigmented coatings. Color and gloss of the coatings were also recorded. The synthesized coating was better at keeping the model building cooler than the Heuback HEUCODUR Black 953. The synthesized pigment performed worse than the Clariant Graphtol Black CLN and about the same as the Heuback HEUCODUR Black 9-100. The testing showed that the synthesized pigment performed better than a commercialized pigment. As more testing is completed, if the synthesized pigment is outperforming commercial pigments, then the synthesized pigment is ready to be taken to market.
