Progress in the Field of Yellow Organic Pigments for High-Performance Applications
The revision of the clean air regulations governing solvent emissions was responsible for the introduction of waterborne paint technology in Germany. This technology was first used in the Bochum plant of Adam Opel AG in 1987 in the new painting line for metallic paints. Shortly afterwards came Volvo's switch to waterborne paints for metallics in Sweden.
In contrast, in the United States high-solid systems are still the majority, with 70%. In Japan, waterborne technology has just become an issue, but with increasing importance in the future. With the introduction of new technologies, new demands for the improvement of organic pigments concerning flow properties, flocculation stability and bleed resistance were raised.
