Description

Sodium Resinate CAS NO 61790-51-0 is the sodium salt of resin acids, primarily derived from pine tree rosin. This versatile chemical compound serves as a crucial emulsifier, tackifier, and dispersing agent in numerous industrial formulations. It is essential for manufacturers in the adhesives, coatings, printing inks, and paper sizing industries seeking to enhance product performance and stability.

Application

• Adhesive Formulations: Acts as a key tackifier and emulsifier in pressure-sensitive adhesives, hot-melt adhesives, and sealants.
• Coatings & Paints: Used as a dispersing agent and flow modifier in water-based and solvent-based coating systems.
• Printing Inks: Functions as a grinding aid and viscosity modifier to improve pigment dispersion and print quality.
• Paper Sizing: Employed in the internal and surface sizing of paper and paperboard to improve water resistance and printability.
• Rubber Industry: Serves as a processing aid and tackifier in the production of various rubber compounds.
• Soaps & Detergents: Utilized as an emulsifying and foam-stabilizing agent in certain specialty cleaning formulations.
• Foundry & Metalworking: Acts as a binder in core and mold making sands within the foundry industry.

Quality Control

Our Sodium Resinate is produced under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Quality parameters including acid value, softening point, color, and solubility are rigorously tested. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids and oxidizing agents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption and caking.
