Rheology of Coatings and Inks

Coatings and inks are two of the most common structured fluids that are characterized on rotational rheometers. Rheometers offer experimentalists many opportunities to perform selected tests that can reveal information about the properties of the fluids and allow one to predict the processability of these systems. Of particular interest are the viscoelastic properties of these fluids at rest to provide information on the stability of these materials and the flow properties of the fluids as the structures are broken and the materials can flow. Insights into these tests will be given, and some new accessories will be discussed that can provide even more information for experimentalists who work with coatings and inks.
