Request SDS →Polyetheramine T-3000 is a trifunctional, amine-terminated polyether triamine based on a propylene-oxide backbone; the grade number tracks approximate average molecular weight. 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 Polyetheramine T-3000 used for?
T-3000 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 T-3000 differ from the difunctional D and ED grades?
T-3000 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 does the 3000 in T-3000 mean?
The grade number tracks the approximate average molecular weight of the triamine. At ~3000 it is a higher-MW, more flexible crosslinker than T-403, giving longer chains between crosslink points and more elastomeric cured networks.
What backbone is Polyetheramine T-3000 built on?
T-3000 is built on a propylene-oxide backbone, which makes it more hydrophobic than the PEG-backbone ED grades. The propylene-oxide chains plus trifunctional amine ends define its flexibility and crosslinking behavior.
What packaging and quantities are available for bulk T-3000?
RawSource supplies T-3000 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.
