Sunlight can be brutal. It wears down even the strongest structures, including rooftops and naval ships, and it heats up metal slides and bleachers until they’re too hot to use. To fend off damage and heat from the sun’s harsh rays, scientists have developed a new, environmentally friendly paint out of glass that bounces sunlight off metal surfaces—keeping them cool and durable.
The researchers present their work today at the 250th National Meeting & Exposition of the American Chemical Society (ACS).
“Most paints you use on your car or house are based on polymers, which degrade in the ultraviolet light rays of the sun,” says Jason J. Benkoski, Ph.D. “So over time you’ll have chalking and yellowing. Polymers also tend to give off volatile organic compounds, which can harm the environment. That’s why I wanted to move away from traditional polymer coatings to inorganic glass ones.”
