This diploma thesis deals with level of degradation of coating layers of car body by contact with chemicals in agreed time periods. First part is focused on surface pre-treatment and coating process in automotive industry. Description of coating materials is following. The last point of first part is focused on alternative coating technology – powder coating what is raising in customers´ focuses because of higher repeatability of powder cloud. The experiment is focused on coating degradation influenced by seven types of chemicals (petrol, diesel, AdBlue, washer fluid, salt liquid, Coca-Cola, alcoholic liquid) what car users meet every day. Testing samples were two bonnets. One was localized inner and another outside. Degradation of coating layer thickness was a long-time term and we measured connection between time of contact and used chemical. Based on such results we were able to determinate level of damage.
