Usage:

Toluene diisocyanate is an organic compound with the formula CH₃C₆H₂. Two of the six possible isomers are commercially important: 2,4-TDI and 2,6-TDI. 2,4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively. It is produced on a large scale, accounting for 34.1% of the global isocyanate market in 2000, second only to MDI. Approximately 1.4 billion kilograms were produced in 2000. All isomers of TDI are colorless, although commercial samples can appear yellow.
