Hexamethylenediamine is mainly used as a monomer to make nylon 6-6. Its derivative hexamethylene diisocyanate (HDI) is used in the production of polyurethane. It acts as a cross-linking agent in epoxy resins. Other applications include fiber, plastics, polyurethane coatings, lubricants, water treatment products and specialty chemicals (biocides, petroleum additives, and phenol purification).
