In the previous article we discussed non-Newtonian fluids and how they perform when measured with efflux cups. Efflux cups are employed in most applications as a benchmark measurement for the fluid in process; they are by no means accurate. Why,

In my recent travels I have encountered a trend that affects inks and coatings resulting in problems that appear to be viscosity-related, when, in fact, they are caused by mixing issues. The non-Newtonian and thixotropic properties of inks and coatings
