Description

Hexadecyl Isocyanate is a long-chain aliphatic isocyanate monomer, a key building block for introducing hydrophobic, reactive NCO functionality into polymer systems. Its primary value lies in its ability to form stable, durable urethane linkages, making it essential for synthesizing specialized polyurethanes, coatings, and surface-modifying agents. This compound is particularly needed by R&D chemists and manufacturers in the specialty polymers, advanced coatings, and adhesives industries seeking to enhance water resistance, flexibility, and chemical stability in their formulations.

Application

• Polymer Synthesis: As a monomer for producing long-chain aliphatic polyurethanes and polyureas with enhanced flexibility and hydrolytic stability.
• Surface Modification: For grafting onto materials (e.g., silica, cellulose) to create hydrophobic surfaces with reactive isocyanate groups for further functionalization.
• Specialty Coatings & Adhesives: A key intermediate in formulating high-performance, moisture-curing coatings, sealants, and adhesives requiring excellent weatherability and chemical resistance.
• Lubricant & Fuel Additives: Used in the synthesis of ashless dispersants and viscosity index improvers that contain urethane or urea linkages.
• Pharmaceutical & Agrochemical Intermediates: Serves as a reagent for introducing the hexadecyl chain into target molecules, potentially for drug delivery systems or agrochemicals.
• Crosslinking Agent: For resins and polymers where a long, flexible spacer between crosslinks is desired to reduce brittleness.

Quality Control

Our Hexadecyl Isocyanate is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including assay by titration and impurity profiling by GC or HPLC, to ensure consistency and high purity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and moisture-sensitive nature, store under a dry inert atmosphere (e.g., nitrogen) in a cool, well-ventilated place. Recommended storage temperature is 2-8°C to maximize shelf-life and prevent polymerization. Keep away from strong bases, acids, alcohols, amines, and other sources of moisture.
