Description

2-Isocyanatooctane is a versatile aliphatic isocyanate monomer, a key building block in the synthesis of high-performance polymers. Its value lies in its ability to impart flexibility, weatherability, and chemical resistance to polyurethane and polyurea coatings, adhesives, and elastomers. This product is essential for manufacturers in the coatings, sealants, and specialty chemical industries seeking to develop durable, high-quality materials. The compound is identified by the CAS registry number 99064-98-9.

Application

• Polyurethane Coatings: A critical raw material for producing light-stable, flexible, and yellowing-resistant coatings for automotive, industrial, and marine applications.
• Adhesives & Sealants: Used to formulate high-performance adhesives and sealants with excellent bonding strength and environmental durability.
• Elastomers: Serves as a monomer in the production of specialty polyurethane and polyurea elastomers for wheels, rollers, and industrial parts.
• Crosslinking Agent: Functions as an effective crosslinker for polymers containing hydroxyl or amine groups, enhancing mechanical properties.
• Chemical Intermediate: Employed in organic synthesis to introduce the isocyanate functional group for further chemical modifications.
• Waterborne Polyurethane Dispersions (PUDs): A key component in the development of environmentally friendly, low-VOC coating systems.

Quality Control

Our 2-Isocyanatooctane is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed against rigorous internal specifications, which typically include assay, isocyanate content, and impurity profile determination. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen or dry air) to prevent polymerization and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
