Coatings that repairs scratches


Autonomic Materials Inc. is going to sell new protective coatings that repair its own scratches. Professors Paul Braun and Scott White from the Institute Beckman belonging to the Illinois University have developed these coatings.

This self-repair system is made up of two polyurethane particles with different functions; one is filled up with polymer building blocks and the other with a catalyst.

As the reactive elements are isolated, it is possible to mix them with an extensive range of coatings.

When a scratch is produced, the microcapsules inside the coating break and their contents flows to the damaged zone forming a polymer that is similar to the bath filler.

There is a huge difference with regard to another self-repair systems, and it is that it does not need high temperatures and humidity to proceed.
