High Viscosity Cellulose Ether Hydroxypropyl Methyl Cellulose HPMC
China Hydroxypropyl Methyl Cellulose Construction Use HPMC

With the development of dry mix mortar, the cellulose ether has become an important admixture for cement mortar. Cellulose ethers are used as thickeners and water retention additives in dry mix mortar applications.

Types of Dry Powder (pre-mixed) Wall Putty Mortar:

Gypsum based and gypsum-lime based machine spray plasters are mixed and applied in continuously working plastering machines. They are used for a highly efficient coating of walls and ceilings and applied in one layer (ca. 10 mm thick).

SLEOCHEM cellulose ethers are essential components of successful cement-based render formulations. render must retain enough water for proper setting of the cement and to achieve high mechanical strength. Celotech cellulose ethers improve water retention of cement-based render and offer these additional advantages:

Cellulose ether is a common additive in dry mortar, which plays a very important role.

Generally speaking, the product descriptions provided by cellulose ether manufacturers will contain the following indicators: appearance, degree of substitution of viscosity groups, fineness, effective substance content (purity), moisture content, recommended areas and dosage, etc.

One of the biggest differences between dry mixed mortar and traditional mortar is to modify dry powder mortar with a small amount of chemical additives. Adding an additive to dry powder mortar is called primary modification, and adding two or more additives is called secondary modification.

Dry mortar generally uses Portland cement as the cementing material, and the amount of cementing material generally accounts for 20% to 40% of the dry powder mortar; most of the fine aggregate is quartz sand, and the amount is large, and it generally needs to be dried and screened.
