- ▸ Epoxy curing agent: Hindered secondary-amine hardener with extended pot life.
- ▸ Polyurea: Slower-reacting chain extender for longer working time.
- ▸ Coatings & adhesives: Controlled-cure reactive amine.
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.
Request SDS →Polyetheramine SD-231 is an amine-terminated polyether diamine with sterically hindered secondary amine end groups on a propylene-oxide backbone, giving slower, more controlled reactivity than the primary-amine grades. As a lower-molecular-weight secondary diamine it functions as an epoxy curing agent and chain extender where extended pot life or gel time is needed. Established applications are in polyurea systems, coatings and adhesives.
Frequently Asked Questions
What is the CAS number of Polyetheramine SD-231?
SD-231 is a polymeric, hindered secondary amine-terminated polyether diamine, so it is specified by grade and approximate average molecular weight rather than a single discrete CAS number. The definitive identity for any supplied lot is stated on its CoA and SDS, available with a quote.
What is Polyetheramine SD-231 used for?
SD-231 is a lower-molecular-weight, hindered secondary-amine polyether diamine used as an epoxy curing agent and chain extender where extended pot life or gel time is needed. It is applied in polyurea systems, coatings and adhesives requiring controlled, slower cure.
How does SD-231 differ from the higher SD grades?
All SD grades share hindered secondary amine ends on a propylene-oxide backbone for slow, controlled cure; the number tracks approximate molecular weight. SD-231 is the lower-MW member, giving higher crosslink density and amine content than higher-MW grades like SD-401 or SD-2001.
Why choose a hindered secondary-amine grade like SD-231?
The sterically hindered secondary amine ends react more slowly than primary amines, extending pot life and gel time. SD-231 is selected when a longer working window is needed before the system gels, with the lower molecular weight giving relatively higher crosslink density.
