Scientists say they have created a new super-white paint that reflects 95.5 percent of the sunlight it hits.
The new acrylic developed at Perdue University is significantly cooler than the surrounding temperature both day and night.
The team designed the paint with calcium carbonate filler to reduce the amount of ultraviolet light paint was absorbed instead of standard titanium dioxide particles.
Researchers say it can be used to keep buildings naturally cold, which will help mitigate climate change due to air-conditioning and other cooling technology.

A new super-white paint (right) developed at Purdue University represents 95.5 percent of the sunlight and remains colder than the surrounding temperature at night and when the sun is at its peak.
To develop a commercially viable paint that is passively cooled, Shilin Ruan, a professor at Purdue’s School of Mechanical Engineering, used calcium carbonate fillers, which reduces the amount of ultraviolet light .
During testing, the new acrylic remained at 10 degrees below the surrounding temperature at night and at least 1.7 degrees Celsius when the sun was at its peak.
other ‘Heat rejects’ White paints only represent about 80 to 90 percent of visible light And at least cannot achieve ambient temperature.
According to a study published this month in Cell Reports Physical Science, when investigated under infrared, calcium carbonate-based acrylic outperformer commercial paint.
New acrylic can be used to keep buildings naturally cold. “This paint can also be used to combat climate change because it rejects sunlight and expands heat in space,” says Professor Shilin Rouan (left) at the Persulus School of Mechanical Engineering Huh.
“Our paint is compatible with the manufacturing process of commercial paint, and the cost can be comparable or even lower,” Ruan says. ‘The key is to ensure the reliability of the paint so that it is viable in long-term outdoor applications.’
Ruan says that paint has many applications, including protecting external telecommunications equipment from overheating.
“This paint can also be used to combat climate change because it deflects sunlight and spreads heat to space,” Ruan said in a statement.
Calcium carbonate-based acrylic distorted other ‘heat-rejecting’ white paint when examined under infrared, and was the only one to achieve low-ambient temperatures

In April, Semple announced that it had created the ‘whitest white’ paint, which reflected 99.6 percent visible light.
