Automotive coatings are not only for aesthetics but, more importantly, to provide comprehensive protection for the vehicle body. The application of silicone oil in the automotive coating field brings unique advantages to the vehicle body, making it have both a shiny appearance and reliable protection performance.

1. Car Paint Coating

• Silicone - containing Car Paint：Silicone - containing car paint is based on traditional car paint with a certain proportion of silicone oil added. During the production process, the silicone oil is evenly dispersed in the resin system of the car paint through special processes. This silicone - containing car paint can be applied to the vehicle body surface by spraying and other methods during construction.
• Performance Characteristics：First, silicone oil can significantly improve the gloss of the car paint. Due to the low surface tension of silicone oil, it enables the car paint to form a more flat and smooth surface during the drying process, like covering the vehicle body with a highly reflective mirror, greatly enhancing the gloss of the car paint and making the vehicle shine brightly in the sun. Second, silicone oil endows the car paint with excellent self - cleaning properties. The contact angle of rainwater, dust, and other pollutants on the surface of the silicone - containing car paint increases, making it difficult for them to adhere. During the vehicle's driving, the washing of rainwater can easily carry away the stains, keeping the vehicle body clean. In addition, silicone oil also enhances the wear resistance of the car paint. It forms a tough protective film on the surface of the car paint, which can effectively reduce scratches caused by stone impacts, tree branch scratches, etc. during daily use, extending the aesthetic appearance and service life of the car paint.

2. Anti - corrosion Coating

• Silicone - based Anti - corrosion Coating：To protect the vehicle body metal from corrosion, silicone - based anti - corrosion coatings are widely used. This anti - corrosion coating usually consists of silicone oil, anti - corrosion resins, pigments, and additives. During construction, it can be evenly coated on the vehicle body metal surface by brushing, spraying, etc.
• Anti - corrosion Principle：The chemical stability and low surface tension of silicone oil play important roles in the anti - corrosion process. On the one hand, silicone oil can form a tight protective film on the metal surface, isolating the contact between moisture, oxygen, and various corrosive substances and the metal, thus preventing the metal from oxidation and corrosion. On the other hand, the low surface tension of silicone oil makes it difficult for water to accumulate on the coating surface, reducing the possibility of electrochemical corrosion caused by the presence of a water film. In addition, other components in the coating, such as anti - corrosion resins and pigments, work together with silicone oil to further enhance the anti - corrosion effect. This silicone - based anti - corrosion coating can effectively extend the service life of the vehicle body, especially in harsh environments such as humidity and acid rain, providing reliable protection for the vehicle body.
