![]() For the waterborne non-Newtonian coatings, the important terms you should keep in mind are pseudoplastic and thixotropic. So while water is a good approximate example of a Newtonian fluid, the formulated waterborne coatings display a high amount of non-Newtonian behavior. Newtonian fluids, like water for example, have a proportional relationship of shear stress and shear rate, meaning the measured viscosity is constant over the measured shear range. This fluid behavior is named after Sir Issac Newton (1642-1727) who first described viscosity as the ratio of the shear stress to the shear rate. ![]() Mitigating Inconsistencies From Liquid Coating Tank Changes
