Scratch-Resistant Clear Coat Preserves a Beautiful Finish
Nissan teamed up with the University of Tokyo and Advanced Softmaterials Inc. to develop Scratch Shield, a special scratch-resistant clear coat (patented in Japan, the United States and Europe).
In addition to its automotive applications, Scratch Shield is now being used as the clear coat for the Style Series N-03B, an NEC mobile phone on the Docomo network in Japan. It is also being considered for various other products, including electrical appliances as well as motorcycles and sporting goods.
Scratch Shield maintains the beautiful finish of a painted surface longer because its highly flexible and elastic properties allow scratches to quickly mend themselves.

A painted surface suffers damage when an external stress tears its polymer chains.
Scratch Shield Technology
The "slide-ring" structure of the clear coat's polymer chains lets them disperse the tension of an external stress, allowing them to remain intact rather than tearing. Over time the chains rebound, causing the painted surface to repair itself.
