A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Polyetheramine D-220 (poly(oxypropylene)diamine, CAS family 9046-10-0) is a low-molecular-weight difunctional polyetheramine, an amine-terminated poly(propylene oxide) with 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 for epoxy resins and as an amine building block for polyurea and polyurethane systems. Supplied as a bulk amine.
Frequently Asked Questions
What is the chemical name for polyetheramine (D-series)?
The D-series polyetheramines are poly(oxypropylene)diamines, amine-terminated poly(propylene oxide) diamines (CAS family 9046-10-0). For D-220, the number approximates an average molecular weight near 220.
What is the CAS number of polyetheramine D-220?
Polyetheramine D-220 belongs to the poly(oxypropylene)diamine CAS family 9046-10-0. Reference this together with the grade designation on any CoA or SDS request to confirm the exact material.
What is Polyetheramine D-220 used for?
It is a low-molecular-weight difunctional polyetheramine used as a low-viscosity curing agent for epoxy coatings, adhesives, and composites. It also serves as an amine building block for polyurea and polyurethane systems.
What is the viscosity behavior of low-MW polyetheramines like D-220?
Low-molecular-weight diamines such as D-220 are low-viscosity liquids, which aids mixing and substrate wetting in epoxy systems. Exact viscosity is grade-specific, so refer to the CoA/TDS for the measured value of the lot you receive.
How is Polyetheramine D-220 supplied and quoted?
It is supplied as a bulk amine liquid in drums, totes, and IBCs under HS 3907.20. Request a bulk quote with your target quantity for current pricing, lead time, and CoA/SDS.
