Advantages Of CMC Applied To Latex Paint

May. 27, 2019

As a Formic Acid Factory, let's share with you the advantages of CMC application in latex paint. As a water retention agent for coatings, CMC can control and adjust the rheology of coatings. It can improve the water retention value of coatings to prevent the migration of water-soluble adhesives. In addition, its excellent film-forming properties make coatings particularly suitable for film transfer coating during size press. Cloth and scraper coating. It is more conducive to overcome the scratch caused by the metering rod or scraper, so that the surface of the coating is smooth and smooth, avoiding the phenomenon of "orange peel". The coating is given good optical properties, opacity, sufficient surface strength, and good K&N values.

CMC For Paper Coating

CMC is also used as an auxiliary adhesive in a large number of coating operations in the paper industry, and it has excellent adhesion. Each CMC can replace 3-4 parts of modified starch or soybean casein, 1.5-2.0 parts of latex, which can reduce the total amount of glue and help to improve the solid content of the coating.

Because CMC has a rigid cellulose backbone and a large hydration volume in colloidal coatings, it is, of course, considered a thickener for coatings. As a thickener, the cellulosic polymer can affect the flocculation state of the pigment particles, thereby affecting the coating structure and coating rheology. The cohesion between the pigment particles depends on the interaction behavior of various components in the coating such as pigments and adhesives, that is, the association between the particles. Most importantly, the adsorption of CMC in the coating greatly affects the structure of the coating and the colloidal binding of the coating.
