| Cas No: | 9046-10-0 |
|---|
| Molecular formula: | (C3H6O)nC3H10N2, n≈68 |
| Introduction: | D-4000 polyetheramine is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure. Polyetheramine D-4000 is a difunctional, primary amine with average molecular weight of about 4000. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains. |
| Applications: | Key ingredient in the formulation of polyurea and RIM
Co-reactant in epoxy systems which require increased flexibility and toughness General polymer flexibilizer |
| Benefits: | Relatively low viscosity, color and vapor pressure
Improved flexibility from high molecular weight polyether backbone Increase peel strength |
