Abstract
Thisarticle discusses results of the next stage of experimental research aimed at developing of an anti-graffiti paint system for passenger rail vehicles. The overriding research task was to meet current European requirements in the field of fire properties with maintaining the desired performance parameters, such as protective and decorative properties. The tests were carried out on samples prepared on a steel substrate. The tests included, first of all, parameters such as flame spreading over the surface and heat emission, the fulfillment of which in the previous studies proved the most difficult. In the described stage of modification work, fire properties of polyester putty on epoxy base were determined. Next, a swellablepaint was applied in the system as an additional protective layer. Research was carried out to find the optimum position of the layer in the entire paint system and its optimum thickness. The tests have shown the effectiveness of the use of a protective paint that allows meeting the requirements in the field of fire safety. In addition, measurements of the surface geometric structure of anti-graffiti coatings were made.
