Description

3-Icosenylsuccinic Anhydride is a high-purity, long-chain alkenyl succinic anhydride (ASA) derivative, a key intermediate in the synthesis of advanced polymers and specialty chemicals. Its primary value lies in its ability to act as a versatile building block for introducing hydrophobic, long-chain alkyl functionalities, thereby modifying material properties like flexibility, water resistance, and adhesion. This product is essential for manufacturers in the polymer, coatings, and lubricant additive industries seeking to develop high-performance materials with tailored characteristics.

Application

• Polymer Modification: Used as a comonomer or chain extender in the production of polyimides, polyamides, and epoxy resins to enhance thermal stability and mechanical strength.
• Corrosion Inhibitors: A critical intermediate for synthesizing high-efficiency oil-soluble corrosion inhibitors used in lubricants and fuel additives.
• Surface Coatings & Inks: Imparts excellent adhesion, flexibility, and water resistance to industrial coatings, paints, and printing inks.
• Paper Sizing Agents: Serves as a key raw material for producing alkyl ketene dimer (AKD) alternatives and other internal sizing agents to control water absorption in paper.
• Lubricant Additives: Employed in the synthesis of succinimide dispersants and other additives that improve the detergency and viscosity index of engine oils.
• Adhesives & Sealants: Enhances the hydrophobic properties and durability of high-performance adhesives and sealants.
• Specialty Surfactants: Acts as a precursor for creating novel surfactants with specific emulsifying and wetting properties.

Quality Control

Our 3-Icosenylsuccinic Anhydride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay, acid value, and impurity profile determination, to meet precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your quality 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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to minimize exposure to moisture and prevent hydrolysis.
