Description

Dodecenylsuccinic Anhydride (DDSA) is a versatile, high-purity organic intermediate primarily used as a curing agent for epoxy resins and as a key building block for specialty polymers. Its long aliphatic chain imparts excellent flexibility, hydrophobicity, and improved impact resistance to the final materials, making it a critical component for advanced formulations. This product is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producers of alkyd resins, plasticizers, and corrosion inhibitors.

Application

• Epoxy Curing Agent: Imparts flexibility and toughness to epoxy systems used in coatings, adhesives, and composite materials.
• Alkyd Resin Modification: Used as a modifying agent to improve the drying properties, flexibility, and water resistance of alkyd resins for paints and varnishes.
• Corrosion Inhibitor Intermediate: Serves as a precursor for synthesizing high-performance corrosion inhibitors used in fuel and lubricant additives.
• Plasticizer Production: Acts as an intermediate in the manufacture of specialty plasticizers that enhance the low-temperature performance of polymers.
• Polymer Synthesis: A key monomer for producing polyesters, polyamides, and other specialty polymers requiring hydrophobic characteristics.
• Paper Sizing Agent: Used in the production of alkyl ketene dimer (AKD) and alkenyl succinic anhydride (ASA) sizing agents for paper manufacturing to impart water resistance.
• Adhesive & Sealant Formulations: Enhances the adhesive strength and environmental durability of industrial adhesives and sealants.

Quality Control

Our Dodecenylsuccinic Anhydride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance, meeting the stringent requirements of industrial applications. A comprehensive Certificate of Analysis (COA) detailing assay, acid value, color, and other critical parameters is provided with each shipment to guarantee traceability and compliance.

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); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can cause hydrolysis. Keep away from strong bases, oxidizing agents, and sources of heat.
