Sodium carboxymethyl cellulose (CMC), grade 2200. Water-soluble thickener and binder for aqueous anode slurries. Used with SBR as the standard water-based binder system, replacing PVDF/NMP and removing the solvent recovery step from electrode coating.

A lot-specific Certificate of Analysis is supplied with every shipment. Values above are the product specification, not single-lot results.
Applications
- Aqueous graphite and silicon anode slurries
- Water-based LFP cathode slurries
- Slurry viscosity control and particle dispersion
Choosing CMC
Grade 2200 sits in the mid-viscosity band at 1500 to 3000 mPa·s, which suits most graphite anode slurries. Higher-viscosity grades give more suspension stability at higher mixing cost; lower grades coat thinner. CMC is normally paired with SBR at roughly 1:1 to 1:2.
Handling
Disperse slowly into water under shear to avoid lumping, and allow full hydration before adding active material. Store sealed and dry.
