Scientists in America have developed what has been described as the “whitest paint currently available.”
The colour was developed at Purdue University in Indiana. Scientists there carried out tests which showed the paint reflects more than 98% of sunlight. The previous whitest paint, created using calcium carbonate, reflected 95.5% sunlight.
Scientists believe it could help save energy. This whiter colour will help keep buildings cool without the need for air conditioning.
White paints currently used for painting buildings typically reflect between 80% and 90% of sunlight. These paints also absorb UV light, which means they’re unable to cool surfaces below certain temperatures.
They believe the paint may go in sale within two years.
