Polyetheramine ED-600 is a difunctional, water-soluble polyether amine epoxy hardener (comparable to Jeffamine ED-600) — a poly(ethylene glycol)-backbone amine giving flexibility, toughness and very low color, with an approximate molecular weight of ~600. Identity: CAS 65605-36-9.
What it is
Polyetheramine ED-600 is a grade-defined difunctional, water-soluble amine-terminated poly(ethylene glycol). As a polymer it is specified by grade and approximate molecular weight (~600) 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 ED-600 is used in waterborne and hydrophilic epoxy systems, coatings 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 ED-600 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.
