Sizing agent: Octadecenyl Succinic Anhydride (0DSA) is used as a neutral sizing agent in papermaking. It has a fast sizing speed and can extend the service life of paper, preventing it from yellowing and becoming brittle Curing agent: Octadecenyl succinic anhydride (0DSA) serves as a curing agent for epoxy resin, playing a sealing and encapsulation role in electronic components. It can enhance bonding strength, increase toughness, improve electrical resistance, and prolong sealing life
Octadecenyl Succinic Anhydride CAS:68784-12-3
Other name:alkenyl Succinic Anhydride
Octadecenyl Succinic Anhydride (ODSA), and Alkenyl Succinic Anhydride (ASA) are highly reactive chemicals with neutral sizing as their core function in papermaking. Their applications cover various pulp sizing scenarios such as cultural paper, white cardboard, and kraft liner board. As a fast-curing sizing agent, ASA forms an aqueous dispersion system through emulsifiers and undergoes esterification reactions with pulp fibers to form chemical bonds. The main product types include Hexadecenyl Succinic Anhydride (HDSA) and Octadecenyl Succinic Anhydride (ODSA)

Octadecenyl Succinic Anhydride CAS:68784-12-3 application
1. As a curing agent for epoxy resin, it plays a sealing and encapsulation role in electronic components, enhancing bonding strength, increasing toughness, improving electrical resistance, and extending sealing life;
2. As a corrosion-resistant lubricant in an anhydrous system, it reduces friction and enhances breakdown temperature;
3. As an additive raw material in metal cleaning, such as solubilizer, rust inhibitor, etc;
4. When added to solvent-based adhesives, it can prevent the corrosion of iron packaging materials by the adhesive solution, without causing the solution to discolor;
5. It can be used as an anti-rust additive for paper sizing agents, corrosion inhibitors, turbine oils, hydraulic oils, etc., with good anti-rust effects.
