Product Overview
Octadecyl Isocyanate, frequently recognized within the chemical industry by its synonymous name Isocyanic Acid Stearyl Ester, represents a high-performance aliphatic isocyanate characterized by a long-chain C18 hydrocarbon structure. This specific molecular architecture imparts significant hydrophobic properties, making it an indispensable reagent for specialized organic synthesis applications. As a premier global manufacturer, we supply this compound with stringent quality controls to ensure consistency across large-scale industrial batches. The compound functions primarily as a versatile building block, enabling chemists to introduce long alkyl chains into various molecular frameworks through reactive isocyanate functionality.
The reactivity of the isocyanate group allows for efficient coupling with nucleophiles such as alcohols and amines, facilitating the creation of urethanes and ureas. This capability is critical for developing advanced materials where surface modification or lubricity enhancement is required. Our production facilities adhere to international safety and quality standards, guaranteeing that every drum meets the specified assay requirements for professional laboratory and manufacturing environments.

Industrial Applications
The primary utility of Octadecyl Isocyanate lies in its role as a critical intermediate for the synthesis of specialty surfactants and lubricant additives. Due to the long stearyl chain, it is exceptionally effective in modifying surface energies, making it ideal for water-repellent coatings and textile treatments. In the lubricants sector, it serves as a precursor for friction modifiers that enhance engine performance under extreme pressure conditions.
- Surfactant Manufacturing: Used to create non-ionic surfactants with enhanced hydrophobic balance.
- Lubricant Additives: Improves wear resistance and viscosity indices in industrial oils.
- Hydrophobic Modification: Grants water-repellent characteristics to polymers and fibers.
- Organic Synthesis: Acts as a reliable reagent for introducing C18 chains into complex molecules.
Storage and Handling
Proper storage is essential to maintain the stability and reactivity of Octadecyl Isocyanate. The product should be stored in a cool, ventilated place away from direct sunlight and moisture sources, as isocyanates are sensitive to hydrolysis. Containers must remain tightly sealed when not in use to prevent exposure to atmospheric humidity. We recommend handling this material with appropriate personal protective equipment, including chemical-resistant gloves and eye protection, in accordance with standard safety data sheet guidelines. Our packaging options include 25 kg drums, with flexibility to accommodate specific customer logistical requirements for global shipping.
