The leveling of the coating film is a manifestation of the apparent performance of the coating. In fact, the leveling of the coating is related to many aspects of the coating, such as viscosity, coating rheology, raw material matching, design of the pigment dispersion process, selection and application of additives Factors such as technology, painting process and painting environment. It can be said that the entire process of coating production and coating is not controlled by the leveling agent alone.
Based on actual work experience, the flow and leveling of the coating and its relationship with the leveling agent are introduced as follows: The role of the leveling agent in the flow and leveling of the coating. Different types of leveling agents have different mechanisms and effects. Even if the types of leveling agents have the same structure, the effects are different. Therefore, the application of leveling agents should be selected according to the problems that the coating needs to overcome and the structural categories of the additives. Pay attention to the compatibility of leveling agents with other additives and their negative effects and countermeasures during application.
Mastering the application of leveling agents will help to improve the quality level of coating products, and the development of leveling agents is also beneficial.
