Full Description

Polyetheramine D-400 (poly(oxypropylene)diamine, CAS family 9046-10-0) is a medium-molecular-weight difunctional polyetheramine, an amine-terminated poly(propylene oxide) diamine of average molecular weight near 400. Its longer chain makes it a flexibilizing curing agent for epoxy resins and a soft-segment amine for polyurea and polyurethane elastomers. Supplied as a bulk amine.

Frequently Asked Questions

What is Polyetheramine D-400 used for?

Polyetheramine D-400 is a medium-molecular-weight difunctional polyetheramine used as a flexibilizing curing agent that adds toughness to epoxy networks. It also serves as a soft-segment amine for polyurea coatings/linings and flexible polyurethane elastomers.

What is polyetheramine?

A polyetheramine is a polyether (here, poly(propylene oxide)) terminated with reactive amine groups. The D-series are difunctional diamines (CAS family 9046-10-0) used as epoxy curing agents and as amine building blocks for polyurea and polyurethane systems.

How does D-400 differ from D-230?

D-400 has a longer poly(propylene oxide) chain (average MW near 400 versus ~230), giving more flexibility and toughness in cured systems. D-230 is shorter and lower in viscosity, while D-400 acts more as a flexibilizing curing agent.

What is the CAS number and HS code for Polyetheramine D-400?

It belongs to the poly(oxypropylene)diamine CAS family 9046-10-0 and is classified under HS 3907.20 (other polyethers, in primary forms). Reference both on CoA, SDS, and customs documentation.

How is Polyetheramine D-400 supplied in bulk?

It is supplied as a bulk amine liquid in drums, totes, and IBCs. Request a bulk quote with your target volume for current pricing, lead time, and CoA/SDS.
