Description

Resin Acids And Rosin Acids, Fumarated, Sodium Salt is a chemically modified rosin derivative where the resin acids have been reacted with fumaric acid and subsequently converted to their sodium salt form. This modification enhances its water solubility and stability, making it a valuable functional additive in aqueous systems. It is primarily utilized in industries such as paper sizing, adhesive formulation, and as a dispersant or emulsifying agent. This product offers improved performance characteristics over unmodified rosin acids, including better compatibility and controlled release properties.

Application

• Paper Sizing Agent: A key internal and surface sizing component to improve water resistance and printability of paper and paperboard.
• Adhesive Formulation: Used as a tackifier and modifier in water-based adhesive systems, including pressure-sensitive and packaging adhesives.
• Dispersing Agent: Acts as a stabilizer and dispersant for pigments and fillers in aqueous coatings, inks, and construction materials.
• Emulsifier: Functions as an anionic emulsifier in the production of synthetic rubber (e.g., SBR) and polymer emulsions.
• Soap and Detergent Industry: Serves as a raw material or additive in the manufacture of industrial soaps and cleaning formulations.
• Textile Auxiliaries: Employed in textile processing as a softening agent, lubricant, or finishing component.

Quality Control

Our production of Resin Acids And Rosin Acids, Fumarated, Sodium Salt adheres to stringent quality management protocols. Each batch is tested against established specifications for key parameters such as acid value, softening point, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting these results are available upon request. We are committed to meeting the quality standards required for industrial applications, including those relevant to the paper and adhesive sectors.

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). This material is hygroscopic (moisture-sensitive) and should be kept away from moisture to prevent caking or degradation. Keep container tightly sealed when not in use.
