The cellulose ether is a polymer compound having an ether structure made of cellulose, and each glucosyl ring in the cellulose macromolecule contains three hydroxyl groups, a primary hydroxyl group on the sixth carbon atom, and a second or three carbon atoms. The secondary hydroxyl group, the hydrogen in the hydroxyl group is substituted with a hydrocarbon group to form a cellulose ether derivative. After etherification, cellulose can dissolve in water, dilute alkali solution and organic solvent, and has thermoplasticity. For more than 60 years, these products have played a significant role in a host of applications, from construction products, ceramics, and paints to foods, cosmetics, and pharmaceuticals.
Grout (cement-based joint filler) is used to fill in the voids between different types of tiles. They can be applied in different widths and many different colors. To minimize shrinkage, the unmodified SLEO type is recommended. SLEO prevents excessive absorption of water into the substrate or ceramic overlay, giving sufficient time for rubbing and finishing.
HPMC plays a role to improve workability, it helps to prevent crack formation and separation of the raw materials in mortar.
Ensure the proper open time of the mortar
Improve sag-resistance and water retention
Provide suitable consistency, excellent workability, and good plasticity
Improve the cohesion of the mortar and its adhesion to the base material
