Tetramethylene diisocyanate

Description:

Tetramethylene diisocyanate (TMDI) is an organic compound characterized by its two isocyanate functional groups attached to a four-carbon chain. It is a colorless to pale yellow liquid at room temperature and has a relatively low viscosity. TMDI is known for its high reactivity, particularly with nucleophiles such as alcohols and amines, making it valuable in the production of polyurethanes and other polymers. The compound has a distinctive, pungent odor and is classified as hazardous, necessitating careful handling due to its potential to cause respiratory irritation and skin sensitization. TMDI is soluble in organic solvents but has limited solubility in water. Its applications extend to coatings, adhesives, and elastomers, where it contributes to the mechanical strength and durability of the final products. Due to its isocyanate groups, TMDI must be managed with appropriate safety measures to mitigate risks associated with exposure.
