What is the viscosity of hydroxypropyl methylcellulose hpmc?

Interior wall putty powder generally has a viscosity of 100,000. Cement mortar has higher requirements for adjustment, and a viscosity of 150,000 is easy to use. In addition, the most critical function of HPMC is to lock in water, followed by thickening. In putty powder, if it has good water retention and low viscosity (7-80000), it can also naturally have a larger viscosity and relatively good water retention. When the viscosity exceeds 100000, the viscosity has little effect on water retention.

The viscosity of hpmc is inversely proportional to temperature, in other words, the viscosity increases as the temperature decreases. The viscosity of the product, the viscosity of the product means that its 2% solution is at a temperature of 20 degrees Celsius, and the test results are.

In specific applications, attention should be paid to areas with large temperature differences between summer and winter, and it is strongly recommended to use lower viscosity in winter. Otherwise, the viscosity is low, the viscosity of the cellulose will increase, and the scratches will be heavy.
