Innovative Industrial Technologies for Preventive Anti-Graffiti Coating

Abstract

Graffiti is the main issue in terms of acts of vandalism with public transport. Hardly any suburban train, commuter train or goods train, hardly any engineering building, station or noise barrier wall escape graffiti spraying. This means enormous expenses every year which one would rather use to the benefit of its customers. Furthermore, the temporary and permanent anti-graffiti protection systems used up to now do not ensure adequate graffiti protection. The costs for the application of graffiti protection and/or graffiti removal to a large part depend on the circumstances of the individual case in question, i.e. on the size of the surface, the type and size of the ground, the accessibility of the location and of the fact whether the graffiti need to be removed from unprotected or protected surfaces. A unique innovation based on nanotechnology can provide a durable graffiti protection on a wide range of surfaces at economical prices. The protection makes the application of lettering, images or signatures significantly more difficult, yet facilitates their removal without any harm to the ground surface.
