KimaCell® CMC FP4000 sodium carboxymethyl cellulose is a kind of ionic linear macromolecular material. The pure product is a white or yellowish fibrous powder. It is non-toxic, tasteless, and easily soluble in cold and hot water to become a transparent viscous solution. It has many advantages that the general natural rubber and synthetic rubber do not have. It is a thickener, adhesive, emulsifier, sizing agent, water retaining agent, dispersibility, suspending agent, expansive fixing agent, retarder, excipient, etc. A small amount of water shall be used to soak it, and then water shall be added and stirred to prepare a solution with the required concentration.

KimaCell® CMC FP4000 sodium carboxymethyl cellulose has a rigid cellulose backbone and has a large hydration volume in colloidal coatings, so it can also be considered as a thickener of coatings. Polymers can affect the flocculating state of pigment particles, thereby affecting the structure and rheology of coatings. The agglomeration between pigment particles depends on the interaction behavior of each component in the coating, such as pigment and adhesive, namely the association between particles. More importantly, the adsorption in the coating greatly affects the structure of the coating and the adhesive force of the coating colloid.
