AMINE APPLICATIONS AND PROPERTIES DATA

JEFFAMINE®

POLYOXYALKYLENEAMINES

JEFFAMINE monoamines, diamines, andtriamines: Versatile in their use and tailorable in theirstructure, these products are used in a variety of chem-istries such as epoxy, curatives, polyamides and otherpolymer derivatives. As epoxy curing agents, they im-part low color, reduce viscosity, and increase flex-ibility, providing cure systems tailored to meet spe-cific requirements. They can be used in preparingpolyamide, polyurea, and modified urethane resins;in adhesives, elastomers, and foam formulations; ascorrosion inhibitors; in agricultural chemical appli-cations; and as intermediates for textile and papertreating chemicals. Polymeric derivatives may be use-ful as dispersants in paints, fuels, and lubricants andas viscosity index improvers for lube oils.
