Description
CMC Ceramic Grade Binder
CMC Ceramic Grade Binder (CAS 9004-32-4, molecular formula R-OCH2COONa) is a raw material for tile, sanitaryware, tableware and refractory production, where particle size and impurity profile drive fired colour and body strength. China Chemicals supplies it at Substitution 0.7 – 0.9 in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as CMC, Sodium Carboxymethyl Cellulose, Cellulose Gum. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Green-strength binder in ceramic tile glaze
- Suspension and anti-settling agent in glaze slip
- Screen-printing medium for ceramic decoration
- Water retention aid in tile adhesive and render
- Thickener in detergent and textile printing pastes
