Hexamethylene Diisocyanate CAS#822-06-0

Hexamethylene Diisocyanate CAS#822-06-0

Basic Information

High Reactivity for Chemical Synthesis: Hexamethylene diisocyanate (HDI) reacts slowly with water, making it suitable for controlled chemical reactions in polymer and coating applications.


Stable Liquid Form: Exists as a colorless or slightly yellow liquid at room temperature, facilitating handling and storage.


Wide Thermal Range: With a melting point of −67 to −55°C and a boiling point of 255–261°C, HDI is stable over a broad temperature range.


Low Solubility in Water: Slight water solubility allows it to maintain performance in formulations where minimal hydrolysis is desired.
