Viscosity is an important parameter of cellulose ether performance. Generally speaking, the higher the viscosity, the better the water retention effect of gypsum mortar. However, the higher the viscosity, the higher the molecular weight of cellulose ether, and the corresponding decrease in its so...Read more »

Self-leveling mortar can rely on its own weight to form a flat, smooth and strong foundation on the substrate for laying or bonding other materials, and at the same time it can carry out large-scale and efficient construction. Therefore, high fluidity is a very significant aspect of self-leveling...Read more »

Relationship Between Water Retention of Hydroxypropyl Methyl Cellulose and Viscosity and Temperature
The water retention capacity of hydroxypropyl methylcellulose depends on the hydroxypropyl content. Under the same conditions, the water retention capacity of high hydroxypropyl methylcellulose is stronger, and the methoxy content of the same hydroxypropyl content is appropriately reduced. . The ...Read more »
