Much as it did for hair styling products and fake tans, spray-on technology now stands to revolutionize everything from locomotives to winemaking to textile design, thanks to a versatile new spray known as “liquid glass.” Applied to nearly any surface, an invisible non-toxic layer of silicon just one millionth of a millimeter thick can protect underlying matter from water, bacteria, dirt and even UV radiation.
Made almost entirely of pure silicon dioxide, liquid glass is harmless to the environment and could replace a variety of harsh cleaning chemicals. The coating can be cleaned with water alone, and tests by food-processing companies have shown that a good hot water rinse left liquid-glass-coated surfaces as sterile as normal surfaces doused with strong disinfecting bleach. The coating is also flexible and breathable, so it can be applied to both static and non-static surfaces.
