SLEOCHEM Cellulose ether is the main additive in ready-mixed mortar. The types and structural characteristics of cellulose ether are introduced. Hydroxypropyl methylcellulose ether (HPMC) is selected as the additive to systematically study the effects on various properties of mortar.

In addition to the adhesion of mortar and substrates obtained by cement, gypsum, calcium hydroxide and dispersible polymer powders, cellulose ethers also provide adhesion.

Each cellulose ether has the basic structure of cellulose-anhydroglucose structure. In the process of producing cellulose ether, the cellulose fiber is first heated in an alkaline solution, and then treated with an etherifying agent. The fibrous reaction product is purified and ground to form a uniform powder with a certain fineness.

As we all know, cement, gypsum or lime based plaster is one of the main applications of cellulose ether. In comparison, HPMC is widely famous in function materials. Today we will study more about the application of SLEOCHEM cellulose ether for wall plaster.

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:
