In recent years the automotive industry has adopted compact process painting process to reduce energy consumption, reduce CO2 generation and reduce operating costs. One such compact process is known as high solid 3-Wet, and it has been published that the 3-Wet process has reduced CO2 emission by 15-25%, VOC emissions by 10%, and reduced process time by 20-25%. Other painting process is known as waterborne basecoat 1 and waterborne basecoat 2, where the primer layer and the bake associated with it has been completely eliminated. The later process not only further reduced these parameters but also reduced the footprints of the new plants. PPG has developed unique polymer architectures which enabled successful launches of these technologies with improved appearance compared to previous painting processes. In this talk, the details of the painting processes and the effect of new polymers on the overall appearance will be discussed.
