Product Description:
D-2000 polyetheramine is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, JEFFAMINE D-2000 polyetheramine is a difunctional, primary amine with average molecular weight of about 2000. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains.

Applications:
Epoxy Systems:
D2000 acts as a curing agent in epoxy systems, contributing to increased toughness and impact resistance in the cured formulation. It's also used as a co-reactant in epoxy systems where increased flexibility and toughness are desired
Polyurea and Polyurethane:
D2000 is a key ingredient in polyurea and RIM (Reaction Injection Molding) formulations. Its fast reaction rate with isocyanates makes it suitable for these applications
Adhesives, Coatings, and Composites:
D2000's properties, such as increased peel strength and toughness, make it valuable in adhesives and coatings. It's also used in composite materials
Storage and Package:
5-35℃with sealing 12 months, other information to MSDS. 200kg/drum
