Polyetheramine D-400 is a difunctional polyether amine epoxy hardener (comparable to Jeffamine D-400) — a poly(propylene glycol)-backbone amine giving flexibility, toughness and very low color, with an approximate molecular weight of ~430. Identity: CAS 9046-10-0.
What it is
Polyetheramine D-400 is a grade-defined difunctional amine-terminated poly(propylene glycol). As a polymer it is specified by grade and approximate molecular weight (~430) rather than a single value; brand names are nominative references to the generic equivalent we supply.
How it cures
Its terminal primary amines ring-open epoxide groups; the flexible polyether backbone builds toughness, flexibility and impact/thermal-shock resistance with very low color and good water resistance. Higher molecular weight gives more flexibility, lower crosslink density and longer pot life.
Applications
Polyetheramine D-400 is used in flexible epoxy coatings, composites and adhesives. Compare other grades: D-230 (rigid), D-2000 (flexible) and trifunctional T-5000.
Forms, grades and handling
Supplied as a clear liquid in drums, IBCs and bulk; grade is defined by molecular weight and functionality. Properties are typical reference values; the Certificate of Analysis (CoA) for the lot you buy governs. Amine curing agents are typically corrosive and can sensitize skin — handle per the current Safety Data Sheet (SDS). Each lot ships with CoA, TDS and SDS.
Bulk supply and RFQ
RawSource sources Polyetheramine D-400 direct from producers in bulk, with CoA, TDS and SDS per lot. Tell us your resin system, cure schedule (ambient or heat) and the properties you need (pot life, Tg, flexibility, chemical resistance), and we will quote the right hardener. See selection logic in the epoxy curing agents guide.

Frequently Asked Questions
What is Polyetheramine D-400 used for?
Polyetheramine D-400 (comparable to Jeffamine D-400) is a difunctional polyether amine epoxy hardener (~430 MW) used in flexible epoxy coatings, composites and adhesives; it gives flexibility, toughness and low color.
How is bulk Polyetheramine D-400 supplied and quoted?
RawSource supplies Polyetheramine D-400 in bulk with CoA, TDS and SDS per lot. Pricing is quote-based on grade and volume; submit an RFQ with your resin system and cure schedule.
What is the REACH and TSCA regulatory status of Polyetheramine D-400?
Polyetheramine D-400 (CAS 9046-10-0) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 618-561-0).
