    Asphalt Additivess

    Amidoamines, made by reacting ethyleneamines with fatty acids, are used in a number of applications, including asphalt additives to improve properties of paved surfaces.

    Bleach Activators

    Since the 1970s, tetra-acetylethylenediamine (TAED) has been widely adopted in Europe for use in powdered detergent compositions as an activator for peroxygen bleaching agents.

  • Img

    Chelating agents

    Polyaminocarboxylic acids and their salts derived from ethyleneamines are used in a variety of applications where specific metal ions interfere with processing, or require buffering, concentrating, separating, or transporting.

  • Img

    Corrosion Inhibitors

    Amidoamines and substituted imidazolines, prepared by the reaction of DETA or TETA with fatty acids, find use as corrosion inhibitors in petroleum production operations.

    Elastomeric Fibers

    Polyurethane elastomeric fiber such as Spandex® and elastane are key components in high performance sports apparel.

  • Img

    Fungicides

    The ethylenebisdithiocarbamates (EBDC's), which were introduced in the early 1940's, represent the most important class of general purpose, broad spectrum fungicides currently used for the control of mildew, scabs, rusts and blights on fruits, vegetables, potatoes, cotton and, to some extent, on grains.

    Lube Oil and Fuel Additives

    A major use of ethyleneamines is in the manufacturing of lubricant and fuel additives. Ashless dispersants are used in engine oils to reduce sludge and varnish deposits caused by the low-speed of motor vehicles.

    Mineral Processing Aids

    Amidoamines, made from fatty acids and ethyleneamines, have been used in the processing of minerals.

  • Img

    Plastic Lubricants

    Ethylenebis (stearamide) (EBS) is a plastic lubricant made by the reaction of one mole of EDA with two moles of stearic acid.

  • Img

    Polyamide Resins

    Thermoplastic polyamide resins made from dimer acid and ethylenediamine are used as hot-melt adhesives and as binders for flexographic or rotogravure printing inks.

  • Img

    Rubber Processing Additives

    EDA is reacted with carbon disulfide, sodium hydroxide and a divalent metal, such as manganese or zinc, to produce dithiocarbamates. Dithiocarbamates are formulated to make various vulcanizing accelerators and promoters.

    Textile Additives

    Uses include applications for man-made and natural fibers and fabrics. Ethyleneamines provide improvements to the properties of dye sorption, adhesion, flame proofing, abrasion resistance, anti-static, and handle.

  • Img

    Urethane Chemicals

    Ethyleneamines are used in the manufacture of polyols and also in the production of catalysts to react polyols with isocyanates. The main applications of these polyols are in urethane systems for appliances, spray foams, building panels and elastomers.

    Drainage Aids

    Flocculants and drainage aids are used to optimize the separation of a solid phase from the liquid phase in aqueous suspensions. Addition of ethyleneamine-based products drastically increase the rate of particle sedimentation so that a clear, supernatant liquid is obtained.

  • Img

    Hydrocarbon purification

    TETA and TEPA are used to purify liquid hydrocarbons, particularly isoprene, by removing small concentrations of carbon disulfide (CS2).

  • Img

    Epoxy Curing Agents

    Ethyleneamines are widely used for curing (cross-linking) epoxy resins both as the pure amine or, more often, as a derivative that contains primary and secondary amines which can react with the epoxy resin functionality.

  • Img

    Fabric Softeners

    Fabric softeners are used to impart softness and antistatic properties to machine washed laundry. These products can be introduced as part of the detergent package, added in the washing machine rinse cycle, or added in the clothes dryer.

  • Img

    Pharmaceuticals

    Ethyleneamines are used as raw materials for the production of several pharmaceutical products, particularly in highly populated, developing nations such as China and India.

  • Img

    Surfactants

    Amphoteric surfactants are mild surfactants used in shampoos that are active over a wide pH range.

  • Img

    Wet strength resins

    Applications for wet-strength resins include paper towels, weather resistant packaging, milk cartons, frozen food packages and vegetable boxes. Products requiring immersion in water such as photographic paper, filter paper and certain textiles in hospital bed sheets and gowns are areas where wet strength is important.
