The most important function is water retention, followed by thickening. In the putty powder, as long as the water retention is good, the viscosity is lower (70-80 thousand) is also OK, of course, the relative water retention of the larger viscosity is better, when the viscosity is more than 100 thousand, the influence of the viscosity on the water retention is not big.
