Ahn et al (2008) mentioned that a high drop in viscosity at the high shear rates (shear-thinning behavior) is also a desired property for cavity filling with less energy, especially for complicated geometries. However, stability of the mixture should be taken into account in order to avoid powderbinder separation.

May 29, 2012 · If you round up a bit, the viscosity at the fastest speed, a fill time of 0.39 sec, is about 2000 psi-sec. If you double the viscosity it would be 4000, five times the viscosity would be 10,000, and 10 times stiffer would be 20,000. So in this case, just by changing injection rate you can change the viscosity 10-fold or an order of magnitude.
