Carboxymethyl Cellulose E466
Carboxymethyl Cellulose Sodium, Carboxymethyl Cellulose, shortly CMC, used as additive in different field,CMC has the fuctions of thickening ,suspending,emulsifying, stabilizing ,shaping, filming,bulking, etc. It can replace the application of guar gum,gelatin and pectin.It is widely used in modern industry,such as food, ceratic,paper making, toothpaste , coating etc.
Dynacel® coating Grade CMC, which 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.

Application
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.
Dosage: 50mg/kg-200mg/kg
FAQ
