1. Primer Selection Based on Body Material Characteristics: Primer selection should adhere to different standards based on the physical and chemical properties of various body materials. For example, steel bodies require primers with excellent adhesion and corrosion resistance to prevent rust formation and spread. When selecting primers for plastic and composite bodies, compatibility with other materials must be fully considered to ensure that the coating adheres tightly while maintaining the original properties of the plastic and composite materials. Primer selection should also consider the primer's application performance and environmental friendliness. High-quality primers should have good leveling and fast drying speeds to ensure coating quality.
2. Employing High-Performance Intermediate Coats to Enhance Protective Barriers: High-performance intermediate coats generally possess excellent filling, leveling, and adhesion properties, effectively compensating for minor surface defects in the primer layer and enhancing the overall smoothness of the coating. This characteristic not only facilitates uniform application of the subsequent topcoat but also reduces topcoat usage and costs within a certain range. Simultaneously, the excellent adhesion of high-performance intermediate coats ensures a stable chemical bond with the primer and topcoat, improving the overall strength and durability of the coating system. High-performance intermediate coats typically also exhibit excellent weather resistance, corrosion resistance, and chemical resistance. During selection, the intermediate coat should also have good application tolerance and be able to be applied stably under various temperature and humidity conditions.
3. Introducing New Environmentally Friendly Topcoats to Enhance Color and Weather Resistance: New environmentally friendly topcoats utilize advanced pigment dispersion technology and curing processes to achieve brighter, more lasting color effects, improving the coating's color performance and weather resistance while reducing harmful emissions, becoming a significant trend in the automotive painting industry. In addition to enhanced environmental friendliness and weather resistance, new topcoats typically possess excellent wear resistance, scratch resistance, and self-cleaning properties. This not only helps reduce damage to the coating from scratches and wear during daily use but also effectively prevents the accumulation of dust, dirt, and other pollutants on the coating surface, keeping the car clean and bright. When introducing new environmentally friendly topcoats, close attention must be paid to their compatibility with primers and intermediate coats. The application performance of new topcoats cannot be overlooked; the coating's leveling, drying speed, and application tolerance directly affect the final coating effect and efficiency.
