Polyetheramine T-403 is a trifunctional, amine-terminated polyether triamine based on a propylene-oxide backbone; the grade number tracks approximate average molecular weight. It is a lower-molecular-weight 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-403 used for?
T-403 is a lower-molecular-weight, 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.
What is the CAS number of Polyetheramine T-403?
T-403 is assigned CAS 39423-51-3, with a representative molecular formula of C17H37NO3, on a propylene-oxide backbone. The definitive identity for any supplied lot is confirmed on its CoA and SDS.
How does T-403 differ from T-3000 and T-5000?
All three are trifunctional propylene-oxide triamines that crosslink epoxies; the number tracks approximate molecular weight. T-403 is the lowest-MW grade, giving higher crosslink density and a stiffer network, while T-3000 and T-5000 are higher-MW and more flexible.
What is the cost of bulk Polyetheramine T-403?
Pricing is volume-, packaging- and freight-dependent and is quoted per order rather than published. Submit your required quantity, packaging and destination for a current bulk quote.
What packaging and order quantities are available for bulk T-403?
RawSource supplies T-403 to manufacturers in drums, IBC totes and bulk volumes. Provide your target volume and ship-to location for current pack sizes, MOQ and pricing, with CoA and SDS available per lot.
