Paints and Anti Graffiti Coating

Graffiti is an expensive social concern for many major cities. Two examples illustrate the scale of the problem: the subway system or the tube in London spends over 15 million dollars per year for cleaning up graffiti and the City of Los Angeles spends even more millions for cleanup work.

Several companies have used nanotechnology to create paints and coatings to help solve the graffiti problem. Some of the products, so far being developed, provide a permanent clear coating that does not allow paint, permanent markers, stickers, graffiti, or any other markings to bond to the coating. The clear coating forms a barrier between the surface of, say, a wall and any graffiti paint that might be applied.
