CMC Usage In The Paint Aquasorb

Paint aquasorb
When combined with its excellent film-forming properties, the coating is particularly suitable for the size press; carboxymethyl cellulose as coating insurance agent, can control and regulate the paint rheology, improve water retention of the coating to prevent the migration of water-soluble adhesives film transfer coating and blade coating, is more conducive to overcome scratch caused by metering blade or bar, the surface of the coating appeared smooth and uniform and smooth, to avoid "orange peel" phenomenon, the coating imparting good optical properties, is not transparency, sufficient surface strength and good K & N value.
CMC is also widely used as an auxiliary adhesive and paper industry coating operation, it has excellent adhesion, each CMC can replace 3 to 4 parts starch or soybean casein, 1.5 to 2.0 parts latex, reducing the overall glue, help improve the coating solids content.
CMC has rigidity because the cellulose backbone, have a greater volume in the hydrated colloidal coating, so naturally considered paint thickener. As a thickener, the cellulose polymer may affect the state of flocculation of the pigment particles, thereby affecting the coating structure and coating rheology. The pigment particles between coagulation are also dependent on the coating such as the role of each component in the behavior of each other pigments and adhesives, i.e., the phenomenon of association between the particles. Most importantly, CMC(Carboxymethyl Cellulose) adsorbed coatings greatly affect the coating structure and coating adhesion colloid.
