Amine-terminated polypropylene glycol trimethylolpropane ether

Amine-terminated polypropylene glycol trimethylolpropane ether, identified by CAS 39423-51-3, is a trifunctional polyetheramine built on a trimethylolpropane backbone.

Commercially recognized as Jeffamine T-403, it functions as a reactive curing agent and crosslinker in epoxy and polyurea systems where its three primary amine groups drive network formation.

In epoxy coatings and flooring systems, this material delivers flexible, tough cured networks with improved impact resistance compared to rigid aromatic amine curatives used in industrial settings.

Adhesive and sealant formulators use it to tune pot life and elongation in structural and flexible bond lines, ensuring high mechanical performance and durability in various applications.

In polyurea and spray elastomer systems, it reacts with isocyanates to produce fast-setting, durable films for protective coatings and industrial linings across the manufacturing sector.

Plastics and polymer compounders also incorporate it as a chain extender or surface modifier to improve adhesion and compatibility at interfaces within complex chemical formulations.

Supplied as a low-viscosity liquid, this product is handled and shipped in drums and IBCs. It is available primarily in technical grade, consistent with industrial curing agent specifications.

Buyers should confirm amine value and equivalent weight with the supplier, as these parameters directly govern stoichiometric calculations required for precise formulation and processing.
