Carboxymethyl cellulose (CMC) has a wide range of applications in aqueous systems.
As a low-cost thickener, carboxymethyl cellulose is used in wall paints, as well as in highly alkaline silicate paints, in which CMC is stable compared to MC.
In the paper manufacturing process
, CMC is used in sizing and coating colours – on the one hand, to adjust viscosity, and on the other, to improve water retention.
CMC acts as a soil carrier when used in laundry detergents and prevents the dissolved soil from settling on the fabric.
Carboxymethyl cellulose is also used in the sizing process in textile production
, either as a component that increases viscosity or as a sizing that can simply be desized with water.
When used in drilling fluids, CMC regulates the flow properties of the drilling fluid and enhances the discharge of the drilling cuttings.
The adhesive properties of moist CMC are used in aqueous adhesives
, especially in paper adhesives.
Carboxymethyl cellulose is available as technical and purified grade with a variety of granulometries and different viscosities.
