Huntsman Performance Products has developed a pioneering polyoxyalkylene diamine. The XTJ-590 product is a fast curing epoxy hardeners at low temperature while providing good mechanical properties to the system. It is a reactive polyether diamine of low molecular weight and can be used in epoxy adhesives, hot melt adhesives, construction chemicals, composites, coatings, polyamide elastomers and epoxy curatives.
As an epoxy curing agent, XTJ-590 polyetheramine provides a cure speed that is approximately four times faster then Huntsman's popular Jeffamine D-230 product and results in cured resins with excellent mechanical properties, impact and thermal shock resistance even at low temperature. It can also be used in polyamides to add flexibility, modify hydrophilicity and improve antistatic properties. This product is much more reactive than all other polyetheramines and is twice as reactive as IPDA.
Formulators will be able to take advantage of the low viscosity and high purity of the XTJ-590 amine. It has the potential to partially replace TETA in polyamide preparation. For optimum properties in epoxy coatings and civil engineering, Huntsman Performance Products recommends that XTJ-590 be adducted and, for low temperature curative systems, further formulated.
