A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Polyetheramine EDR-148 is a short-chain, fast-reacting polyether diamine corresponding to 2,2'-(ethylenedioxy)diethylamine, triethylene glycol diamine (CAS 929-59-9). The compact, ether-linked backbone gives high reactivity, making it useful as a reactive chain extender and curing agent. Established applications are in polyurea systems and epoxy formulations where rapid cure is required.
Frequently Asked Questions
What is Polyetheramine EDR-148 used for?
EDR-148 is a short-chain, fast-reacting polyether diamine used as a reactive chain extender and curing agent. Its high reactivity makes it a cure-speed modifier in polyurea systems and a fast-curing amine in epoxy formulations where rapid set is required.
What is the chemical identity of EDR-148?
EDR-148 corresponds to 2,2'-(ethylenedioxy)diethylamine, also called triethylene glycol diamine, CAS 929-59-9, with molecular formula C6H16N2O2. The compact, ether-linked backbone is what gives it high reactivity compared with the longer polymeric grades.
Why does EDR-148 react faster than the ED or D-series amines?
EDR-148 is a short, discrete diamine with primary amine groups separated by a compact ethylene-dioxy bridge, so the amine groups are highly accessible and there is little chain bulk to slow reaction. The longer polymeric ED and D grades cure more slowly because of higher molecular weight and steric effects.
What packaging and order quantities are available for bulk EDR-148?
RawSource supplies EDR-148 to manufacturers in drums, IBC totes and bulk volumes. Available pack sizes and minimum order quantity depend on current sourcing; request a bulk quote with your target volume and destination.
Can you provide a CoA and SDS for EDR-148?
Yes. A Certificate of Analysis for the supplied lot and the current Safety Data Sheet are provided with each order. Request both with your quote so you can confirm identity (CAS 929-59-9) and handling information before purchase.
