Synthetic resin

In the adhesives industry, Carboxymethyl Cellulose (CMC), typically used in its sodium salt form (CMC-Na), serves as a versatile water-soluble polymer that functions primarily as a thickener, stabilizer, and film-forming agent. It is extensively employed in water-based adhesives, such as those used for paper binding, wallpaper pastes, and packaging applications, where it imparts the necessary viscosity for easy application while maintaining strong initial tack. CMC also enhances the open time of adhesives, allowing for extended working periods before setting, and improves the mechanical stability of the adhesive formulation. Additionally, its film-forming properties contribute to a flexible, coherent bond line upon drying, ensuring reliable adhesion across various porous substrates.
