WebFigure 1. Three-step flow method: viscosity behavior of a thixotropic material Figure 2 shows an example of measuring the thixotropic properties of a blue paint at 25 °C. The test is conducted on a Discovery Hybrid Rheometer using a 40 mm parallel plate geometry. The three-step flow test is designed as follows: Webbehavior of the material may change as a result of these f o r c e s . If the shear rate changes during an application, the internal structure of the sample will change and the change in stress or viscosity can then be seen. Typical flow curves are shown in F i g u r e 2. Newton-ian flow (A curve) is the simplest type, displaying a
