What is it?
Triethylenetetramine is a mixture of four compounds. These compounds are:
• L-TETA (N,N’-bis(2-aminoethyl)-1,2-ethanediamine)
• DAEP (N,N’-bis-(2-aminoethyl)piperazine)
• PEEDA (N[(2-aminoethyl)2-aminoethyl]piperazine)
• TAEA (tris-(2-aminoethyl)amine)
It is primarily used as a hardener in epoxy curing.
How do I avoid it?
You should avoid any contact with this substance. Avoidance requires reading labels, package inserts, and, on occasion, direct communication with the manufacturer.
Uses:
• Curing epoxy resin-based coatings, adhesives, laminates, grouts, etc
• Lubricating oil – Engine oils and other lubricants
• Fabric softeners – Ethyleneamine-based fabric softeners are commonly added to textile materials to make them less harsh,
“softer” or more pleasing to the touch.
• Textile processing – Permanent press, shrinkproofing wool, static prevention, and mothproofing. Dye assistance.
• Asphalt additives – Antistrip additives promote adhesion between the mineral aggregate and the asphalt in mixtures for road
paving, patching, and surfacing.
• Paper wet-strength resins – The leading types of resins used to impart wet-strength properties to various types of paper
are made with ethyleneamines. Paper so treated is used in tissue and toweling products, packaging for milk and other food
items, as well as filter papers, photographic paper, and various non-woven products.
• Fuel additive
• Mineral processing aids
• Petroleum chemicals – A number of ethyleneamine derivatives are used in petroleum production and refining operations as
corrosion inhibitors, demulsifiers, neutralizers, and functional additives. Corrosion inhibitor formulations use a significant
volume of ethyleneamines.
• Polyamide resins – Polyamide resins find wide use as binders in printing inks on certain paper, film, and foil webs.
• Hot-melt, pressure-sensitive, and heat-seal adhesives for leather, paper, plastic, and metal.
• Glossy, abrasion-resistant, overprint varnishes
