| General Description
Ortho-toluenediamine (OTD) is a high purity aromatic diamine. Physically, OTD is light gray 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
OTD is used as an intermediate in the manufacture of polyols, antioxidants, corrosion inhibitors, rubber chemicals and dyes. In addition, in many applications OTD is an acceptable alternative to the higher priced ortho-phenylenediamine. These applications include epoxy resin curing, polymer initiating, crosslinking, and chain extending and capping. Availability
OTD is available in:
- 55 gallon non-returnable drums
- 5,000 gallon tank trucks
- 5,000 gallon isocontainers
- 20,000 gallon tank rail cars
