Jeffamine® THF-170 Polyetheramine

Jeffamine® THF-170 Polyetheramine by Huntsman is diamine of approximately 1700 molecular weight. It is chemically based on a PTMEG [poly(tetramethylene ether glycol)]/PPG (polypropylene glycol) copolymer. It contains a significant amount of secondary amine as well as primary amine. It is useful in a variety of polymers including cured epoxy resins, polyurea and polyamides. It is effective in flexibilizing and promoting adhesive peel strength in epoxy formulations. It has also been used to improve flexibility and low temperature properties of polyamides. Jeffamine® THF-170 Polyetheramine provides improved mechanical properties, improved anticorrosion property and its amine end group is more reactive than alcohol. It is listed in TSCA.
