Description

Octadecylsuccinic Anhydride is a high-purity, long-chain alkenyl succinic anhydride (ASA) derivative, serving as a versatile hydrophobic agent and chemical intermediate. Its primary value lies in its ability to impart water repellency and modify surface properties in various industrial materials. This product is essential for manufacturers in the coatings, adhesives, and polymer industries seeking to enhance product performance and durability.

Application

• As a key hydrophobic agent and sizing chemical in the production of paper and paperboard.
• As a corrosion inhibitor and surface modifier in protective coatings and primers.
• As a reactive intermediate for synthesizing epoxy curing agents, plasticizers, and surfactants.
• In the formulation of adhesives and sealants to improve moisture resistance.
• As a compatibilizer and processing aid in polymer blends and composites.
• In the manufacture of alkyd resins to modify flexibility and drying properties.
