J18 is a C18 alkenyl succinic anhydride (ODSA) designed for high-performance internal sizing in paper products requiring enhanced water and oil resistance.
C18 long-chain alkenyl structure delivers excellent hydrophobic and oleophobic performance.
Ideal for use in internal sizing formulations requiring enhanced water and oil resistance.
Provides stronger hydrophobic sizing effects than C16 ASA in high-performance paper applications.
Suitable for coated board, food packaging paper, and specialty papers with barrier functions.
Requires controlled emulsification; best used in freshly prepared ASA emulsions.
High-purity grade ensures stable sizing efficiency and minimized hydrolysis during storage.
| Property | Value |
| Appearance | Light yellow to amber transparent liquid |
| Content | ≥95% |
| Acid value (mg KOH/g) | 320-380 |
| Hexadecene Content | ≤3.0% |
| Maleic Anhydride Content | ≤0.5% |
| Moisture | ≤0.05% |
| Density (g/cm³) | 0.90-1.00 |
| Color (Fe-Co) | ≤10 |
Used as a curing agent for epoxy resin in electronic components, providing sealing and encapsulation, enhancing bonding strength, improving toughness, increasing electrical resistance, and extending seal life.
Serves as a corrosion-resistant lubricant in anhydrous systems, reducing friction and raising breakdown temperature.
Acts as an additive in metal cleaning, such as solubilizers and rust inhibitors.
Added to solvent-based adhesives to prevent corrosion of iron containers and avoid discoloration of the adhesive solution.
Used as a rust inhibitor additive in paper sizing agents, corrosion inhibitors, turbine oil, and hydraulic oil, providing excellent rust prevention.
