CMC Painting Grade

1.Painting grade sodium carboxymethyl cellulose (CMC)Made from natural cotton fibers, through etherification, purification and drying process, Sodium carboxymethyl cellulose (CMC) has good water solubility, having the functions of thickening, stabilizing emulsifying and suspending in aqueous solution. So can be widely used in the painting industry.CMC in painting industry can help the coating equally distributed, improve rheological property and adjust the paint viscosity. 2.Commodity informationName: Carboxymethyl Cellulose (CMC)Other name: Sodium Carboxymethyl cellulose (SCMC); Na-CMC; Carboxy Methyl Cellulose; sodium salt of Carboxymethyl Cellulose; Carboxymethylcellulose sodium; painting grade CMCMolecular formula: C8H16NaO8CAS No.: 9004-32-4HS CODE: 391231003. Function in detergent field1) Good thickener in painting industry. 2) Can match most of the surface-active agents and preservatives exist in the water-soluble painting.3) Change the rheological properties of the coating.4) Prevent the drippage and sagging during the using process.4. Characteristics a) Finely powder and low free fibersb) High transparency of the solutionc) Good compatibilityd) Easy soluble in watere) Nontoxic, odourless, harmless to physical body.5.
