摘要： The invention relates to a substrate provided with a multilayer coating. The invention additionally relates to a process for its preparation, in which the body to be coated passes via the entry 1 into the pretreatment stage 2. This is followed by electrodeposition coating 3 and the baking 4 of the electrodeposition coat. In stage 5 preparation takes place for coating with powder coating material (stage 6). In stage 7 drying is carried out with IR irradiation. This is followed by the cooling stage 7. The powder coating material is applied to the powder coat in stage 9. Following passage through the intermediate drying stage 10 a protective coat is applied in stage 11 and then is baked in stage 12. The body is transported out of the unit via the exit 11.
