April 21 , 2021 1448 days 813 0
  • US engineers have created the whitest ever paint.
  • The ultra-white paint is made up of barium sulphate.
  • That makes it whiter.
  • It can also cool surfaces 8 degrees Fahrenheit below their surroundings under strong sunlight during noon hours.
  • The paint can keep surfaces 19 degrees Fahrenheit cooler than their ambient surroundings at night.
  • This paint may be the closest equivalent to the blackest black paint called “Vantablack”.
  • That is able to absorb up to 99.9 per cent of visible light.
