The new paint keeps the building cool in the hot sun.

News: the sun like fire, will damage the super structure, scorched metal slides and open-air watches high temperature can not be used. To protect against hot sunlight, researchers at Johns Hopkins University in the United States have developed a new eco-friendly glass
coating,
, that reflects sunlight, keeps buildings cool and makes them more robust.
team presented the results at the 250th National Conference and Expo of the American Chemical Society (ACS) on the 16th.Dr Jason,
of the university's Applied Physics Laboratory, said: "Most of the paint used in cars or houses is polymer-based and degrades under the sun's ultraviolet rays, which can turn powdered and yellow over time. Moreover, polymers tend to release volatile organic matter that harms the environment. So we wanted to move from traditional polymer coatings to inorder glass coatings. Glass
made of silicon is an ideal coating, it is durable and has the right optical properties. However, it is very fragile. In order to add this particular layer to the new coating, Jason began using silicon, one of the most abundant materials in the earth's crust, Physicists Network reported on August 16. He improved potassium silicate, which is usually dissolved in water, and made the compound into a silicate-mixed "paint" that would be waterproof when sprayed to dry surfaces.
like acrylic, polyurethane or epoxy coatings, which are almost completely inormeric and more durable than other coatings that contain organic compounds. It is designed to expand and contract with metal surfaces to prevent cracking. It also has a prominent feature: its ability to reflect all sunlight and passive radiant heat. Because it doesn't absorb sunlight, any surface painted with this paint will keep it warm or even slightly cooler, which is the key to protecting the building's structure from sunlight.
, the researchers developed the new paint, which was originally intended for naval vessels, but found that it had many potential uses for commercial applications.
Jason said: "You can apply this paint to your own roof, keep the temperature and reduce the billing figures for summer air conditioning, and you can use it on metal slides or open-air stands. And its price is affordable because the raw materials needed make it rich and cheap. "
