The growing demand for automobile production has raised the market size of the additives. The population of the whole of Europe is about 502 million, and it is expected to increase to 733 million by 2017. Population growth will not only drive the process of urbanization, but will also increase the growth of automobile demand. With the increase of automobile production, the demand for automotive coatings and coating additives will be further increased.
The control of volatile organic compounds (VOC) has promoted the diversion of solvent based coatings to water-based coatings. Although VOC emissions of waterborne coatings are less, their rheological properties and dispersivity are poor, and a large number of fungi and bacteria can be detected when they are stored and attached to the coating surface. It can be seen from this that a large number of auxiliaries are needed to meet the high quality of water based coatings. The application of water-based coatings has greatly increased the demand for auxiliaries.
New technological trends provide an opportunity for product innovation. The paint manufacturers have launched a series of new product formulations, and these new product formulations require the use of new additives. For example, the application of powder coatings has stimulated the growth of new additives in recent years.
The demand for high quality coatings increases the application of coating additives. High quality coatings can improve the aesthetic value of cars, and some important properties of coatings, such as rheological properties, dispersivity and defoaming properties, can only be achieved through auxiliaries. Therefore, as a necessary condition for improving the performance of the coatings, the automotive coatings additives are essential.
