New Paint Formulation Keeps Surfaces Cooler than Previous Ultra-White Paints Written by AZoBuildApr 16 2021 In an attempt to mitigate global warming, engineers from Purdue University have produced the world’s whitest paint. An infrared camera shows how a sample of the whitest white paint (the dark purple square in the middle) actually cools the board below ambient temperature, something that not even commercial 'heat-rejecting' paints do.

In October 2021, the researchers produced an ultra-white paint that pushed the limitations of the facet of white paints. Now, the team has exceeded those limitations. Not only is the newer paint whiter but it can also keep the surfaces cooler than the formulation previously demonstrated by the team.
