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-2001 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 higher-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 Polyetheramine SD-2001 used for?
SD-2001 is a higher-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 that require a longer working window.
Why does SD-2001 react more slowly than primary-amine grades?
Its end groups are sterically hindered secondary amines on a propylene-oxide backbone, which are less reactive than primary amines. This gives slower, more controlled cure and longer pot life, useful when more working time is required before gel.
What backbone is Polyetheramine SD-2001 built on?
SD-2001 is built on a propylene-oxide backbone, making it more hydrophobic than the PEG-backbone ED grades. The propylene-oxide chain plus hindered secondary amine ends defines both its solubility behavior and its slower reactivity profile.
What is the identity of Polyetheramine SD-2001?
It is a polymeric, hindered secondary amine-terminated polyether diamine, defined by grade and approximate average molecular weight rather than a single discrete CAS number. Lot-specific composition is documented on the CoA and SDS supplied with material.
What packaging and quantities are available for bulk SD-2001?
