Toluene Diisocyanate is commonly used as a cross-linking agent in the manufacture of Nylon Polymers

Toluene diisocyanate used in the production of polyurethane foams, elastomers, coatings; paints; varnishes; wire enamels; sealants; adhesives, and binders.

Toluene Diisocyanate is Denser than water. Flammable, but may be difficult to ignite. TDI Vapors are heavier than air.

TOLUENE DIISOCYANATE resulting during polymerization reaction with strong bases or acyl chlorides.

TDI Reaction with aniline may generate enough heat to ignite unreacted portion and surrounding materials.

TDI Reaction with water liberates carbon dioxide. Potential explosion if stored in polyethylene containers due to absorption of water through the plastic. Emits toxic fumes of oxides of nitrogen when heated to decomposition.
