Request SDS →Polyetheramine D-205 (poly(oxypropylene)diamine, CAS family 9046-10-0) is a low-molecular-weight difunctional polyetheramine, an amine-terminated poly(propylene oxide) carrying two terminal primary amine groups; the 'D' denotes a diamine and the number approximates its average molecular weight. It is used as a low-viscosity curing agent (hardener) for epoxy resins and as an amine building block for polyurea and polyurethane systems. Supplied as a bulk amine.
Frequently Asked Questions
What is Polyetheramine D-205 used for?
Polyetheramine D-205 is a low-molecular-weight difunctional polyetheramine used as a low-viscosity curing agent (hardener) for epoxy coatings, adhesives, and composites. It is also an amine reactant for polyurea and polyurethane systems.
What is the chemical name for Polyetheramine D-205?
It is a poly(oxypropylene)diamine, an amine-terminated poly(propylene oxide) carrying two terminal primary amine groups (CAS family 9046-10-0). The 'D' denotes a diamine and the number approximates the average molecular weight.
Why is D-205 used as an epoxy curing agent?
Its two terminal primary amine groups crosslink epoxy resins, while its low molecular weight gives low viscosity for easy mixing and wetting. This makes it suitable for epoxy coatings, adhesives, and composite systems.
What is the HS code for Polyetheramine D-205?
It is classified under HS 3907.20 (other polyethers, in primary forms). Verify the exact tariff line for your destination country with your customs broker.
How is Polyetheramine D-205 packaged for bulk supply?
It is supplied as a bulk amine liquid in standard industrial packaging such as drums, totes, and IBCs. Request a bulk quote with your target volume for pricing, lead time, and CoA/SDS.
