Viscosity, in particular non-Newtonian viscous behavior, is an important material property
that contributes to a fluid’s performance. Because paints are rendered pseudoplastic, they
show high stability during storage. Settling is avoided due to the supporting higher
viscosity at low shear (gravity) conditions. A relatively high viscosity at low shear rates
means also that higher amounts of paint can be held on a brush without dripping. Pumping
and general mixing of ingredients are carried out at low to medium shear rates. Application
of the paint or coating generally happens under relatively high shear conditions (brushing,
spraying). Here a lower viscosity is beneficial
