Description

n-Hexadecenylsuccinic Anhydride is a high-purity, long-chain alkenyl succinic anhydride (ASA) derivative, a critical intermediate in advanced polymer synthesis and surface modification. Its core value lies in its bifunctional reactivity, enabling it to act as a versatile building block for creating tailored materials with specific hydrophobic, adhesive, or corrosion-resistant properties. This compound is essential for manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance product performance and durability.

Application

• Corrosion Inhibitor Precursor: A key intermediate for synthesizing high-performance corrosion inhibitors used in fuel and lubricant additive packages.
• Epoxy Curing Agent & Modifier: Imparts flexibility, hydrophobicity, and improved adhesion in epoxy resin systems for coatings, composites, and electronic encapsulants.
• Paper Sizing Agent: Used in the production of alkyl ketene dimer (AKD) and ASA-based sizing agents to impart water resistance to paper and paperboard.
• Polymer Additive: Functions as a plasticizer, compatibilizer, or cross-linking agent in various polymer formulations, including polyesters and polyamides.
• Surfactant & Emulsifier Synthesis: Serves as a hydrophobic intermediate for producing specialty surfactants with unique surface-active properties.
• Adhesive Formulation: Enhances tack, peel strength, and water resistance in hot-melt and pressure-sensitive adhesive formulations.
• Research & Development: A valuable building block in organic synthesis for creating novel monomers, dendrimers, and functional materials.

Quality Control

Our n-Hexadecenylsuccinic Anhydride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, acid value, and color determination, to ensure consistency and compliance with agreed specifications. Certificates of Analysis (COA) documenting purity and key physical-chemical parameters are available for every shipment upon request.

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 and degradation upon contact with atmospheric moisture.
