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.Technical Parameters:
| Colorless to pale yellow liquid with slight haze permitted |
| 25 max |
| Primary amine, % of total amine | 97 min |
| Total acetylatables, meq/g | 0.98 – 1.1 |
| Total amine, meq/g | 0.98 – 1.05 |
| Water, wt% | 0.25 max. |
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
