Abstract:

The article describes the technology and application of anti-graffiti coating systems for rolling stock, i.e. coatings resistant to devastation by graffiti-vandals and easy to be renovated later. Paint systems for rolling stock must fulfill mechanical and qualitative properties to longer maintenance protective and decorative properties on the vehicle. Graffiti spray paints should be treated as dangerous substances for coatings because they contain various solvents and other substances that might soften or migrate into protective coating and cause delamination of the coating system and finally lead to shortening durability of the coating surface. Surface free energy is of interest in the field of coating technologies and cleaning procedures, because it is a factor which affects such surface properties and interfacial interactions as adhesion, adsorption and wetting. The contact angle of a liquid on a solid surface is a measure of a free surface energy so the study of wettability and free surface energy is of great practical interest in industrial processes, especially for paints with special properties like anti-graffiti for rolling stock industry. This paper presents results of the investigation on the free surface energy for the anti-graffiti BO100-AGR coating developed in laboratory of Barwa Company. The system consists of high solid corrosion protection primer, putty, filler, basecoat and anti-graffiti clearcoat. The research was based on anticorrosion coatings system with transparent layer with reduced adhesion of each subsequent types of contamination.
