Description

1-Dodecenylsuccinic Anhydride is a versatile alkenyl succinic anhydride (ASA) derivative, a key intermediate in the synthesis of high-performance polymers and additives. Its reactive anhydride group enables it to function as an effective corrosion inhibitor, curing agent, and hydrophobizing agent, making it critical for enhancing material durability and performance. This product is essential for manufacturers in the coatings, adhesives, epoxy resin, and lubricant industries seeking to improve product longevity and resistance to environmental factors.

Application

• Corrosion Inhibitors: A primary component in rust-preventive oils, greases, and fuel additives, forming a protective layer on metal surfaces.
• Epoxy Curing Agents & Hardeners: Used to cure epoxy resins, imparting flexibility, chemical resistance, and improved adhesion in coatings and composites.
• Paper Sizing Agents: Acts as an alkyl ketene dimer (AKD) alternative for internal sizing, enhancing paper's resistance to water and ink.
• Lubricant & Fuel Additives: Serves as a dispersant and anti-wear agent, improving the performance and lifespan of industrial lubricants and fuels.
• Polymer Modification: Employed as a comonomer or grafting agent to modify the properties of polyesters, polyamides, and other polymers.
• Adhesives & Sealants: Enhances the tack, water resistance, and durability of hot-melt and pressure-sensitive adhesives.

Quality Control

Our 1-Dodecenylsuccinic Anhydride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, acid value, and color determination, to ensure it meets precise specifications for reactivity and purity. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and 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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent hydrolysis of the anhydride group by atmospheric moisture.
