Supplied for industrial formulation and manufacturing use; not for retail or consumer sale.
Values shown are typical for the current commercial grade. A lot-specific Certificate of Analysis accompanies every shipment; the grade-specific SDS is available on request.
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 →Polypropylene Glycol Monoamine is a polyether monoamine — a single amine-terminated poly(propylene glycol) (~2000 MW) used as a reactive modifier, chain stopper, dispersant and surfactant building block. Identity: CAS 83713-01-3.
What it is
Polypropylene Glycol Monoamine (CAS 83713-01-3) is a grade-defined polyether monoamine with one terminal primary amine on a poly(propylene glycol) chain. The monofunctionality makes it a modifier/chain stopper rather than a crosslinker.
How it cures
Its single amine reacts into epoxy or with isocyanates as a chain stopper or reactive flexibilizer, and its polyether tail gives surfactant/dispersant and water-compatibility properties — used to modify networks and as a building block.
Applications
Polypropylene Glycol Monoamine is used in reactive surfactants, dispersants and hydrophobic modifiers in epoxy and PU. Difunctional grades for crosslinking: polyoxypropylenediamine at ~230 MW and ~2000 MW.
Forms, grades and handling
Supplied as a clear liquid in drums, IBCs and bulk; grade defined by molecular weight. 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 Polypropylene Glycol Monoamine 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.
Typical Properties
