CHICAGO (Reuters) - Scientists have developed a polyurethane coating that heals its own scratches when exposed to sunlight, offering the promise of scratch-free cars and other products, researchers said on Thursday.
Scratch-proof cars on the way?
Mar. 12 - Imagine a scratch on a car that heals itself.
A new polymer coating which repairs itself in sunlight is illustrated under UV light in this time-lapse video. The process takes about 30 minutes.
The coating can be applied to vehicles, packaging, or any surface that is exposed to the environment and sunlight.
