Paint Grade Sodium Carboxymethyl Cellulose is a type of water-soluble polymer that is used as a thickener, binder, and stabilizer in various types of paints and coatings. It is derived from cellulose, which is a natural polymer found in plants. This is used to improve the rheological properties of the formulation, such as viscosity, flow, and leveling and also helps to improve the adhesion and durability of the paint film. Paint Grade Sodium Carboxymethyl Cellulose is available in different viscosity grades, which can be selected based on the specific application and formulation requirements.
