Description

1,10-Diisocyanatodecane is a linear aliphatic diisocyanate monomer, a key building block in polymer chemistry. This compound matters for its ability to form high-performance polyurethane and polyurea materials with excellent hydrolytic stability and mechanical properties. Industries requiring durable, flexible, and chemically resistant polymers, such as specialty coatings, adhesives, and elastomers, rely on this monomer. Its long, flexible hydrocarbon chain contributes to the final polymer's toughness and low-temperature performance.

Application

• Polyurethane Synthesis: Primary monomer for producing linear and cross-linked polyurethanes used in high-performance elastomers, coatings, and adhesives.
• Specialty Coatings: Key component in formulating abrasion-resistant, flexible, and chemical-resistant coatings for automotive, industrial, and marine applications.
• Adhesives & Sealants: Used in the production of high-strength, moisture-curing polyurethane adhesives and sealants with excellent bonding properties.
• Elastomer Manufacturing: Essential for creating castable and thermoplastic polyurethane elastomers (TPU) for gaskets, wheels, and industrial parts.
• Polyurea Coatings: Reacts with polyamines to form fast-curing, durable polyurea coatings for protective linings and spray-applied systems.
• Chemical Intermediate: Serves as a versatile intermediate for further organic synthesis, including the creation of specialty polymers and dendrimers.

Quality Control

Our 1,10-Diisocyanatodecane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay by titration and impurity profiling, to meet precise customer specifications. A Certificate of Analysis (COA) detailing all relevant parameters is provided with every shipment to support your quality assurance protocols.

Storage

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