Request SDS →Polyoxypropylenetriamine (Mn ≈ 3000) is a trifunctional, amine-terminated polyether triamine based on a propylene-oxide backbone. It is a higher-molecular-weight, flexible crosslinker whose three reactive amine ends act as a crosslinking epoxy curing agent and network former. Established applications are in polyurea and polyurethane elastomers, composites, coatings, adhesives and sealants.

Frequently Asked Questions
What is Polyoxypropylenetriamine (Mn ≈ 3000) used for?
This grade is a higher-molecular-weight, flexible trifunctional polyether triamine used as a crosslinking epoxy curing agent and network former. Its three reactive amine ends build crosslinked networks in polyurea and polyurethane elastomers, composites, coatings, adhesives and sealants.
How does this grade differ from difunctional polyetheramines?
This grade is trifunctional, with three amine ends per molecule, so it crosslinks into a network rather than just extending chains the way a diamine does. The higher functionality raises crosslink density and toughness in cured systems.
What backbone is Polyoxypropylenetriamine (Mn ≈ 3000) built on?
This grade is built on a propylene-oxide backbone, which makes it more hydrophobic than PEG-backbone polyetheramines. The propylene-oxide chains plus trifunctional amine ends define its flexibility and crosslinking behavior.
What packaging and quantities are available for bulk Polyoxypropylenetriamine (Mn ≈ 3000)?
RawSource supplies this grade to manufacturers in drums, IBC totes and bulk volumes. Request a quote with your target volume, packaging and ship-to location for current MOQ and pricing, with CoA and SDS provided per lot.
What is the REACH and TSCA regulatory status of Polyoxypropylenetriamine, Mn ≈ 3000 (CAS 64852-22-8)?
Polyoxypropylenetriamine, Mn ≈ 3000 (CAS 64852-22-8) is listed as Active on the U.S. EPA TSCA Inventory; its REACH registration status is not determined from the public ECHA registry.
