The great importance of dispersing processes becomes apparent when one tries to formulate a coating without dispersants. The chemical and physical nature of the additives and fillers we use in our coating systems causes the particles to interact with each other. This is desirable for the finished coating, but complicates the manufacturing process. Understanding the principles,one needs something to stop these interactions, at least temporarily. When pigments and fillers are dispersed, agglomerates that have formed during storage and transport are broken up and converted into primary particles. In the process, the forces of attraction ...
