| General Description
Meta-toluenediamine (TDA) is a high purity aromatic diamine that contains over 99% meta-isomers and less than 0.3% ortho-isomers. Physically, TDA is light yellow in color and will tend to darken upon storage as well as if exposed to air. It also exhibits a slight ammonia-like odor. Applications
TDA finds its primary commercial market as an intermediate in the manufacture of toluene di-isocyanate (TDI), the predominate isocyanate used in flexible polyurethane foam and elastomers. TDA can also be used as a monomer, chain extender, crosslinker, or intermediate in many applications where the more expensive meta-phenylenediamines are currently used. These applications include epoxy resin curing, polyol manufacturing, use in rubber chemical and dye production and use in polyamides/polyimides. Availability
TDA is available in:
- 55 gallon non-returnable drums
- 5,000 gallon tank trucks
- 5,000 gallon isocontainers
- 20,000 gallon tank rail cars
