Product Description

Sodium Carboxymethyl Cellulose (also referred as CMC and Carboxy Methyl Cellulose) can briefly be described as an anionic water-soluble polymer produced from naturally occurring cellulose by etherification, substituting the hydroxyl groups with carboxymethyl groups on the cellulose chain.

Being readily dissolved in hot or cold water, Sodium Carboxymethyl Cellulose CMC can be produced in different chemical and physical properties.

These properties can affect the performance of the product (CMC) in the application, furthermore can be essential for optimizing the production costs.
 

There are a number of parameters which define the properties of the Sodium Carboxymethyl Cellulose CMC.

√ Purity (active CMC content): inevitably CMC powder is produced with by products that are sodium salts which comes in the product Sodium Carboxymethyl Cellulose content in the product is the purity.

√ Viscosity: one of the most interesting characteristics of the CMC powder is the viscosity which can be from low to high. It is measured mostly by digital viscometers at certain temperatures in different solution rates; such as 1%, 2% or 4%.

√ Degree of Substituion: is the average number of sodium carboxymethyl groups per anhydroglucose unit on the cellulose back bone. This parameter in some application areas is quite important to control in the product.

√ Physical form: the CMC powder can be produced in fine powder to dust-free granule.

CMC Paint Grade:  
CMC is macromolecule compound with multichain, and the linear chain will open, spread, interact and form the network collide after the water swelling. Meanwhile, the macromolecule chain with oxhydryl has hydration with water and twine with each other, and then increase the water phase viscosity. It has the excellent compatibility in water or in organic solvent, as well as the pigment. It used as thickener, dispersant and stabilizer in coating industry. It usually can replace the Hydroxyethyl Cellulose HEC in Latex paint.

1. Application in regular coating
CMC' s oxhydryl macromolecule chain has hydration with water and twine with each other, and then increase the water phase viscosity. It has the excellent compatibility in water or in organic solvent, as well as the pigment. It also can greatly improve the viscosity and rheology, and it used as thickener, dispersant and stabilizer in coating industry. CMC which is applied in water-solube coating will show the effect as follows:
*Good water resistance and filming durability;
*High fullness of filming, well-distributed of filming, and highlight acquirable,
*As the stabilizer, it can prevent the paint-coat from being apart due to the abrupt change of the temperature ;
*As the protective colloid, it can maintain the stability of coating system in the wider range of pH value;
*As the thickener, it can make the coat well-distributed, and achieve to the expected viscosity for storage and construction, and avoid the serious stratification during the period of storage.
*Enhance the coat leveling property, anti splash and anti sagging, so that improve the construction workability;
*Make the additives like pigment and filler be dispersed in the coat and the coat will show the excellent effect of pigment adhesion.

2. Application in latex paint
Latex paint mainly composed of polymer water dispersion and pigment water dispersion. Its viscosity has the influence on settleability, brushability, roll coating, fullness of film, levelling property and the sagging property on the film vertical surface, so it will often adjust the viscosity and rheology of latex paint. While CMC has the advantages of good rheology, small resistance of brush coating, easy for construction, and thus it used as the stabilizer, thickener and water retention agent.
*Good thickening effect, high efficiency for latex paint thickening
*Be with stability property., and make the paint a certain viscosity with no residue in storage;
*Make the moisture permeate the porous substrate slowly, and maintain the water when the latex content is high;
*Less limitation on paint formula, small effect by collide type, dispersant and surface active agent;
*Coating finishes, and the water action with the CMC will terminate. Regain the viscosity and avoid sagging.

3. Application in casting paint
CMC is macromolecule compound with multichain, and the linear chain will open, spread, interact and form the network collide after the water swelling. CMC can interact with the sodium base bentonite, and it not only improve the suspending power of sodium base bentonite, but also dramatically reduce the volume of the sediment agglomeration, furthermore, it prevents the fire intolerant aggregate from sinking. Thus, it always used as to enhance the suspensibility rate of the casting paint, and improve the paint viscosity.
*Excellent water-solube viscosity increasing, and improve the coating viscosity and rheology;
*Good solubility and dispersion, making the solids suspend in the carrier liquid;
*Impel the fire intolerant powder suspend and avoid settling, layering and the carrier liquid excessive penetration into the molding material;
*Promote the spreading and covering power of paint, and enhance its brushing property and leveling property;
*The powder bonds with each other after dried, and adheres firmly on the inside and outside surface

4. Special products for coating grade
C2000R has a good ability to resist divalent ions and the glue with C2000R can enhance the stability of white cement and not easy to be mildewed.

Detergent grade CMC:
CMC can be used as THICKENER / thickening agent for liquid detergents, thickening agent for soap.

Detergent grades are mainly used in powder and cream type for detergent production, as well as in soap making industry.  
With the character of emulsifying and gel protection, CMC will produce the anion during washing and it makes the washed surface and the dirt granule be negatively charged. It prevents re-sticking of the dirt which will be removed by detergent during the cleaning rinsing process. So, the dirt granule has the phase separation property in aqueous phase, and has the repellency with the washed material surface of solid phase. Place dirt then deposit on the washed material, and it can make the white textile keep the whiteness and colored textile bright. CMC can replace hydroxyethyl cellulose (HEC) and Hydroxy propyl methyl cellulose (HPMC)  as THICKENER for liquid detergents, which can reduce production cost.

In making soap, adding an appropriate amount of CMC helps to greatly improve the quality of soap. It enables soap to be pliable and flexible and thus convenient for pressing and processing.

The different types of detergent grades of CMC are produced in the limits of detergent grade specifications but they will be divided into different variations due to customer demands. The customer satisfaction, price sensitivity and other expectations are fully covered by these variations.
