The GM 9984145-1990 standard specifies the technical requirements and performance indicators of moldable automotive exterior coatings. The Coatings are used for surface preparation of automotive exteriors and require excellent weathering resistance, corrosion resistance, marring resistance and color Stability to adapt to different climate and environment conditions. In addition, the Coatings need to have good adhesion and molding performance to ensure that no coating peeling or damage occurs during the body forming process. The standard also includes requirements for the construction process, drying time and environmental adaptability of coatings, providing automobile manufacturers with a complete mass assurance system to ensure the durability and aesthetics of vehicle external coatings in long-term use.
