1. Use in putty In putty powder, HPMC plays three major roles of thickening, water retention and construction. Thickener: The cellulose thickener acts as a suspending agent to keep the solution uniform up and down and prevent sagging. Construction: HPMC has a lubricating effect, which can make th...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 »

As the most important admixture in building dry-mixed mortar products, cellulose ether plays a key role in the performance and cost of dry-mixed mortar. There are two types of cellulose ethers: one is ionic, such as sodium carboxymethyl cellulose (CMC), and the other is non-ionic, such as methyl ...Read more »

The improvement of mortar properties also has different effects. At present, many masonry and plastering mortars have poor water retention performance, and the water slurry will separate after a few minutes of standing. So it is very important to add cellulose ether in cement mortar. Let’s ...Read more »
