What’s the appropriate viscosity of hydroxypropyl methyl cellulose (HPMC)?

A: The wall putty powder is generally 100000 Mpa.s, the mortar requirements are higher,and 150,000 Mpa.s can be used.

Moreover, the most important role of HPMC is to retain water, followed by thickening. In the wall putty powder, as long as the water retention is good, the viscosity is lower (7-80,000), it is also possible, of course, the viscosity is larger, the relative water retention is better, when the viscosity exceeds 100,000, the viscosity has little effect on the water retention. Absolutely is also better, and the viscosity is large, and it is better to use in cement mortar.
