Now this paint has the potential to cool the exteriors of airplanes, cars or trains. In an effort to curb global warming, Purdue University engineers have created the whitest paint yet. In spring last year, a team from Purdue unveiled the first ultra-white painta product so white that it set a Guinness World Record. Purdue researchers create the world's whitest white paint Without the building heating up, air conditioning wouldnt have to kick on. The formulation that Ruans lab created reflects 98.1% of solar radiation at the same time as emitting infrared heat. Typical commercial white paint apparently gets warmer rather than cooler and these intrepid scientists wanted to reverse that to help fight climate change and curb energy use. This research was supported by the Cooling Technologies Research Center at Purdue University and the Air Force Office of Scientific Research through the Defense University Research Instrumentation Program (Grant No.427 FA9550-17-1-0368).

Whats more, air conditioners typically work by removing heat from indoor spaces and pushing it outdoors, a method known as convection. Coating buildings with this paint may one day cool them off enough to reduce the need for air conditioning, the researchers say. Now, that's a cool color: Purdue researchers create the world's whitest "Madeline Stuart, designer principal of Madeline Stuart Associates. Researchers hope the paint will be available for purchase from a major retailer in the future. These readings confirmed that our paint has a lower temperature than both its surroundings and the commercial counterpart, Ruan said. The lead researcher behindthewhitest paint ever madesays the highly-reflective paint is on trackto be sold to the generalpublic, who could someday cool their homes simply by painting their roof. The whitest paint ever went for sale starting Thursday, Sept. 16. Its a lot of area, but if one day we need to use this approach to help reverse the warming trend, its still affordablethe paint is not expensive, Ruan says. An infrared camera image shows that white radiative cooling paint developed by Purdue University researchers (left, purple) can stay cooler in direct sunlight compared with commercial white paint. In the meantime, its easy for sustainable building experts to envision the potential future impacts of this invention. UPDATE: Purdue University researchers create the whitest paint on record.
