The viscosity of a material according to the rate at which it
is sheared, provides important information about processing
and performance. This can be important in production where
stirring, dispensing and pumping of the product will subject
it to a variety of shear rates. Low shear rate behavior can be
related to storage conditions of materials: sedimentation,
phase separation, and structure retention. Single point
viscosity information does not profile the material across a
spectrum of shear rates. Materials that may behave the same
at one end of the flow curve may show dramatic difference
at the other, which relates to structural differences in these
materials as shown in Figure 11 for two adhesive dispersions
