塗装のレオロジー

抄録

Paints are manufactured by dispersing raw materials. Paint films are formed via coating, drying, and curing process. In other words, the functions of paints express after a lot of processes. To control the processes mentioned above especially coating process, altering the rheological properties of paints is effective. In this session, we introduce the application of rheology through some examples in practice. First, we explain why rheology is useful for controlling each process. Then, we introduce the relation between each process and the shear rate in steady flow, which is usually measured in order to control the processes. Finally, we explain the development of spatter-less paint for roller-coating based on rheological analysis, which is a good example of industrial application of rheology.
