DYTEK® EP (1,3-Pentanediamine, DAMP)* |
|
|
|
| Product Description |
|
| A low viscosity, low odor, biodegradable, liquid diamine featuring an odd carbon, ethyl-branched, asymmetric structure and differential amine reactivity.
|
|
|
|
|
| Features |
|
Flexibility
As a comonomer or a curative, DYTEK® EP offers lower polymer viscosity, crystallinity and Tg. Flexibility and polymer free volume are increased by incorporating the ethyl side branch.
Fluidity
DYTEK® EP has a very low glass point, -117°C. Many low MW derivatives will also be liquids at or below ambient temperatures. For high MW derivatives, melt points are lowered.
Reactivity
The terminal amine group is 100 times more reactive than the ethyl-hindered amine group. The reaction of a variety of reagents with the terminal amine occurs with greater than 9:1 selectivity.
Rheology
In formulated products the very low viscosity of Dytek® EP and its derivatives can improve flow, penetration, wetting, or solubility over straight chain diamines.
