Formulators in the adhesives, coatings, and related industries face challenges both in optimizing production efficiencies and achieving superior toughness and flexibility properties in the final product. Are you satisfied with your production and your products’ properties in your formulations? A solution exists that solves these challenges!
JEFFAMINE EDR-148 polyetheramine by Huntsman is a symmetrical, unhindered diamine. Like other JEFFAMINE polyetheramines, it imparts flexibility and toughness to thermoset polymers. However, JEFFAMINE EDR-148 polyetheramine is unique in that it is much more reactive than the JEFFAMINE D, T, and ED series amines. This increased reactivity results in faster cure times which saves formulators time and costs in production.
• Low viscosity – Used as a reactive diluent in epoxy formulations
• High purity – Suitable as a molecule for synthesis of high-purity chemicals/intermediates
• High reactivity – Provides fast cure in epoxy adhesives
• Flexible and hydrophilic – Used as a monomer in polyamide applications instead of ethylene amines
• Thermal shock resistant – Suitable for epoxy electronic encapsulation, increasing life cycle of devices
• EHS profile – Not listed as a substance of very high concern
