The new paintwork reflects up to 98% of infrared radiation. The car painted with this enamel does not heat up and the interior stays cool.
Scientists from the American Purdue University have developed an innovative white paint. It is able to reflect the sun's rays, so the cars painted with it do not heat up even in the heat. This is reported by the website of the university.
Scientists have been working on a new paintwork for several years. Recently, the invention got into the Guinness Book of Records as “the world's whitest paint”.
Experiments have shown that white enamel can reflect up to 98.1% of sunlight and infrared radiation. The surfaces painted with it do not heat up. On the contrary, their temperature is 4.5 degrees lower than the ambient temperature.
The developers claim that such a paintwork allows you not to turn on the air conditioner in a car, bus or plane in the heat – the interior remains cool. This will save fuel and reduce harmful emissions into the atmosphere.
The new paint was presented a year ago and it was intended only for the walls of buildings. The fact is that the enamel contained barium nitrate and worked only when applied in a thick (400 micron) layer. The coating turned out to be too dense and heavy.
However, this year it was decided to replace barium nitrate with boron nitride, which significantly improved the characteristics of the paint. Now, to reflect the sun's rays, a thin enough layer (100-180 microns) is enough, that is, it is already possible to cover the body of a car or the fuselage of an aircraft with enamel. It even turned out to be 80% lighter than traditional car paints, because it contains miniature air bubbles.
The new enamel is almost ready for mass production. It is quite possible to establish it in the coming years.
