An introduction to rheological additives for coatings
Rheology – from the Greek rheos - is the study of flow and is used to describe the deformation of a material under stress. The effects of rheology can be seen everywhere; compare oil, honey, and bitumen, all are liquids yet each flows very differently. Controlling rheology is crucial for the paint formulator to not only provide enhanced application properties but also to provide long term stability. In this technical article, we will discuss the fundamental principles of rheology, how this relates to coatings, and will take a closer look at materials that can be used to modify flow behaviour.
