- ▸ 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 →Secondary Polyether Diamine (Mid-Molecular-Weight) 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 mid-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 Secondary Polyether Diamine (Mid-Molecular-Weight) used for?
It is a mid-molecular-weight amine-terminated polyether diamine with sterically hindered secondary amine end groups, 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 cure.
Why does this secondary polyether diamine cure more slowly than primary-amine diamines?
Its end groups are sterically hindered secondary amines on a propylene-oxide backbone, which are inherently less reactive than primary amines. This produces slower, more controlled cure and a longer working window before gel.
What is the identity of Secondary Polyether Diamine (Mid-Molecular-Weight)?
It is a polymeric, hindered secondary amine-terminated polyether diamine, defined by grade and average molecular weight rather than a single discrete CAS number. Lot-specific identity is on the CoA and SDS supplied with the order.
What packaging and quantities are available for bulk Secondary Polyether Diamine (Mid-Molecular-Weight)?
