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