The just-experienced global economic recession has made most automakers caught off guard and struggling to cope with the backlog. The vibration in the automotive industry has brought direct impact to the coatings industry. European and American industry insiders believe that after the crisis baptism, the automotive coatings industry's focus shifted from innovation to efficiency and cost reduction, simplifying the application process is the key to getting rid of the crisis.
"I don't think the paint industry has returned to normal right now. Production materials for automotive coatings and paints such as polyester, acrylic, polyurethane (PU), rings," said Chris Harold, director of industrial product management for PPG, the European automotive OEM. Oxygen resins and melamine, etc. are currently being sold slowly and are expected to remain difficult in the next few years. By 2012, it will be difficult for us to see market growth. It will take longer before going back to the peak before the financial crisis. Now everything is going from costs and Start with efficiency."
Harold said that simplification of the automotive paint application process can significantly increase efficiency, which is the main goal of the next five years. It takes time to paint in a variety of processes, and people are working to shorten the process or cancel some processes while maintaining the original performance.
The body of an automobile is usually first subjected to a series of soaking or spraying by an original equipment manufacturer (OEM), ie, pretreatment, electrophoretic paint, primer, topcoat, and varnish treatment, which are expensive and time consuming. Paint manufacturers such as PPG are striving to simplify the complex process and hope to save the primer process while maintaining performance. Harold said that the cancellation of the process not only saves a lot of time, but also saves materials, labor costs and energy consumption, and significantly reduces costs. Almost every OEM is now conducting a project study in this area. He also said that simplifying the process has become the mainstream of research and development, and has made great progress in the past few years. However, the removal of the primer also presents some challenges because the primer has two main advantages. First, it enhances the scratch resistance; second, it protects the electrophoretic paint. Simplifying the process means that the topcoat must be able to block ultraviolet light from penetrating the electrophoretic paint and also have good scratch resistance.
In recent decades, dazzling innovative paint coatings have been introduced into the automotive industry and have grown into a multi-billion dollar industry. From scratch resistance to color change, to self-repair paint, new products continue to emerge. According to Lothar Karl, head of Bayer MaterialSciences, corrosion and scratch resistance have been the focus of attention for the past 20 years. In addition, the coatings industry is also working to reduce emissions of volatile organic compounds (VOCs) and carbon dioxide. He said that this is a gradual process, and every improvement is faced with technical challenges. The anti-scratch and anti-corrosion properties of automotive paints have not yet reached the level desired by the automotive industry – ultra-high gloss surfaces, with almost no visible scratches like glass. He believes that in terms of technology development, 90% of the companies can achieve their goals within 2 to 3 years, but it will take several years to actually introduce this technology into the production line.
Carl also said that there are many ways to increase efficiency and save costs. In addition to the elimination of primers, changing the traditional heat-curing method to UV-curing is another long-term goal. In the traditional thermal curing process, the car passes a 140°C long-distance Oven. If the UV lamp is replaced, at a lower temperature, it only takes a few minutes to cure the automotive surface coating, thereby greatly increasing the production efficiency and obtaining a strong scratch-resistant surface layer.
