Description

2,5-Furandione, Polymer With 1-Octadecene, C20-28-Alkyl Esters is a polymeric alkenyl succinic anhydride derivative, a versatile chemical intermediate prized for its hydrophobic and reactive properties. This compound is engineered to provide superior performance as a dispersant, corrosion inhibitor, and surface-modifying agent in demanding industrial formulations. It is a critical raw material for manufacturers in the coatings, lubricant additives, fuel treatment, and polymer modification sectors seeking to enhance product stability and functionality.

Application

• Lubricant & Fuel Additives: Acts as a highly effective dispersant and detergent in engine oils and industrial lubricants to prevent sludge formation and deposit control.
• Coatings & Inks: Functions as a pigment wetting and dispersing agent, improving color development, gloss, and stability in solvent-based paint and ink systems.
• Corrosion Inhibition: Used in rust preventive oils and metalworking fluids to form a protective hydrophobic film on metal surfaces.
• Polymer Modification: Serves as a reactive intermediate for the synthesis of alkyd resins, polyesters, and other polymers, imparting flexibility and water resistance.
• Adhesives & Sealants: Enhances adhesion to low-energy surfaces and improves the compatibility of various formulation components.
• Paper Sizing: Employed in the production of alkyl ketene dimer (AKD) analogs for internal sizing to improve water resistance in paper products.

Quality Control

Our production of 2,5-Furandione, Polymer With 1-Octadecene, C20-28-Alkyl Esters adheres to a stringent quality management system. Each batch is analyzed to ensure consistent performance characteristics such as saponification value, viscosity, and active content. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve product integrity. Keep away from strong bases and oxidizing agents.
