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.
The use of CELOTECH cellulose ether optimises the following properties:
1) Easy mixing without lump formation
Celotech cellulose ethers as additives are vital when dry powder products are mixed by hand. The lubricating properties of Celotech cellulose ethers reduce friction between particles, saving time and making thorough dispersion easier.
2) Improved workability
The lubricity of Celotech cellulose ethers improves workability, making spreading easier and increasing efficiency. Users also prefer the "feel" that cellulose products give to tile adhesives and grouts.
3) Good water retention
Cellulose ethers increase the water retained by the adhesive, minimizing the amount absorbed by the substrate and by the tile. This prolongs open time, and brings gains in productivity because the adhesive can be applied to a wider area. Celotech cellulose also can extend shelf life and pot-life of ready-mixed adhesives, prolonging their usefulness.
4) Enhanced adhesion and sliding resistance
Celotech cellulose products enhance adhesion, even at high ratios of water to solids, ensuring a better result and preventing sagging. Celotech additives can help your products resist sliding, a benefit that tile setters will appreciate.
5) Heat resistance
Redispersible polymer powders can be included in formulations using Celotech cellulose ethers to ensure that adhesives offer bonding strength after exposure to heat.
