| Résumé : |
The new coating system is based on a graft polymer of an acrylic resin onto a silicon resin. Both the acrylic and the silicon resin need adapted polarities, molecular weight distributions and functionalities. A special synthesis route allows the introduction of a variety of functional groups and to combine the novel graft polymers with various crosslinking systems. The most predominant property of the new polymers is a very low surface tension which remains unchanged over a couple of years. The chemical and mechanical properties of the resulting coatings were investigated extensively. Coatings based on the described graft polymers show an excellent dirt repellent effect, graffities can be easily removed only with water. Therefore a long range of possibilities in the field of application is revealed; practical experiences are made with application of an anti graffiti clear-coat on trains in Denmark and Germany. |
