Request SDS →Secondary-amine-terminated polyoxypropylenetriamine is a trifunctional, amine-terminated polyether triamine with sterically hindered secondary amine end groups on a propylene-oxide backbone, giving slower, more controlled cure than the primary-amine triamines. Its three reactive ends act as a crosslinking epoxy curing agent and network former with extended pot life. Established applications are in polyurea systems, coatings and adhesives.
Frequently Asked Questions
What is secondary-amine-terminated polyoxypropylenetriamine used for?
This grade is a trifunctional, amine-terminated polyether triamine with sterically hindered secondary amine end groups, used as a crosslinking epoxy curing agent and network former with extended pot life. It is applied in polyurea systems, coatings and adhesives where slower, networked cure is needed.
What makes this triamine a crosslinker rather than a chain extender?
This grade is trifunctional, with three reactive amine ends rather than two, so each molecule can bond to three epoxy or isocyanate sites and build a crosslinked network instead of just extending a chain. The hindered secondary amine ends slow that crosslinking for longer gel time.
How does this triamine differ from the difunctional secondary-amine diamines?
Both use hindered secondary amine ends on a propylene-oxide backbone for slow, controlled cure, but the secondary-amine diamines are difunctional while this grade is a trifunctional triamine. The third reactive end makes this grade a network-forming crosslinker rather than a linear chain extender.
What is the identity of this secondary-amine-terminated polyoxypropylenetriamine?
This grade is a polymeric, hindered secondary amine-terminated polyether triamine, specified by grade and average molecular weight rather than a single discrete CAS number. Definitive lot identity appears on its CoA and SDS, supplied with the order.
What packaging is available for bulk secondary-amine-terminated polyoxypropylenetriamine?
