This method describes a procedure for measuring high shear viscosity of pigment coating colors using a High-Shear Viscometer with a capillary configuration.
In this method, high shear viscosity is determined as mPa·s at the shear rate of 500,000 s−1, and simply called Capillary Viscosity.
The method is applicable for water-based pigment coating colors used in various coating processes such as in blade, rod, and film transfer coating. Typically, suitable pigment coating colors have a solids content between 30 % and 80 %, and they contain mineral pigments, synthetic and / or natural binders and coating additives.
