Application of aluminum pigments in automotive coatings

    Automotive paint refers to the paint painted on the bodies and parts of various vehicles such as cars. It generally refers to the paint and auxiliary materials of new cars and paint for vehicle repair. The application of aluminum silver pulp in automotive paint is mainly used in automotive topcoat. In the past 50 years, automotive topcoat has changed greatly in terms of base material, topcoat color and construction. It is mainly manifested in the base material from nitro magnetic paint to amino alkyd magnetic paint, and the primer uses self-dry alkyd resin magnetic paint to thermoplastic acrylic resin magnetic paint. Among them, the thermosetting acrylic resin magnetic paint and polyurethane stain resistance have been greatly improved, which improves the protection performance of the topcoat. At the same time, the color of the topcoat is becoming more and more diverse, and the appearance of various types of cars is also richer. By the 1990s, more and more attention had been paid to environmental protection around the world, and car topcoat began to change to water-based car topcoat. Car topcoat is mainly Magnetic paint, mostly high gloss, has good mechanical properties and weather resistance. At present, the bodies of high-end cars and cars mainly use amino resins, acrylic resins, alkyd resins, polyurethane resins, medium-solid polyesters, etc. as the base materials. Inorganic pigments such as titanium dioxide, phthalocyanine pigments and organic pigments with bright colors and good weather resistance are selected. In addition, some additives are added to achieve satisfactory appearance and performance. At present, China also basically uses solvent-based automotive topcoat. Some Western developed countries have adopted waterborne automotive topcoat.

    Automotive paint generally refers to the original paint of the car, the repair paint of the car, the interior paint of the car, and the exterior paint of the car. It is mainly used in the painting of different parts of cars such as sports cars, sedans, buses, trucks, vans, etc.; car engines; car bumpers; car hubs; car chassis and other different parts of cars.
