United States. Scientists at Johns Hopkins University, who belong to the department of applied physics, have invented a paint that bounces sunlight (even on metallic materials) which makes a surface stay colder and can increase its useful life.
Due to the effect that the sun causes with heat, the structures deteriorate more easily, which makes this development an important fact for the sector. As explained by Jason J. Benkoski, who led the study which was presented at the American Chemical Society about a year ago: "Most paints found in cars or homes are based on polymers, which degrade with the ultraviolet light rays of the sun. So over time they will yellow and degrade. In addition, polymers also tend to emit volatile organic compounds, which can harm the environment."
One of the advantages of this paint is that it is almost inorganic, which differs from acrylic or otherwise, thus favoring its durability. It is designed to expand and contract on metal surfaces to prevent cracking and with the extra quality of reflecting all sunlight. In addition, it will keep the surface cooler, at air temperature or even cooler.
"If we make a paint that can keep an outdoor surface close to the air temperature, then you can reduce the rate of corrosion and other types of degradation. You may want to paint the roof of your home to maintain freshness and reduce your air conditioning bill in summer."
