SHANDONG YUCHENG YI AO TECHNOLOGY CO., LTD

Alias: 1,6-diisocyanatohexane; 1,6-Hexamethylene diisocyanate; 1,6-Hexanediol diisocyanate; 1,6-hexylene diisocyanate; 
Product name: hexamethylene diisocyanate (HDI)
CAS   No.: 822-06-0
Molecular formula: C9H18O2N2
Melting point: -67℃
Boiling point: 122℃ (1.33KPa) ;
Structural formula:

O=C=N-(CH₂)₆N=C=O

Properties: colorless transparent liquid, with slightly pungent odor, flammable, soluble in benzene, toluene and other organic solvents.
Uses: mainly used for the production of polyurethane coatings, elastomers, adhesives, textile finishing agents. There are also a wide range of applications  in aviation, foam plastics, coatings, rubber industry, etc. Its polyurethane coatings not only own good oil and weather resistance, but also own the features as non-yellowing, color-retenting, glossiness-retenting, anti-chalking and excellent resistance to outdoor exposure, which are far better than that of aromatic polyurethane coatings. It has been widely used in the finishing of aircraft, automobiles, railway vehicles, ships, machine tools, etc. In addition, HDI is also used in curing agents of coatings, polymer crosslinking, low viscosity adhesives of printing pigment paste, collar copolymer coating, immobilized enzyme adhesives, and dyeing processing of polyester, coating agents of leather and textile and finishing agents, etc.
