JEFFAMINE D-205
JEFFAMINE D-205
JEFFAMINE® D-205 amine is a difunctional primary amine with oxyalkylene units. It is designed to be a low amine hydrogen equivalent weight polyetherdiamine with slower curing speed than conventional polyetheramines. It is well fit for applications where low viscosity, low exotherm and longer pot life are desirable.
For applications where a slower curing speed is beneficial, JEFFAMINE D-205 amine is similar in AHEW and structure to JEFFAMINE D-230 amine. However, its primary amines are more hindered, making it slower to react with epoxy groups. JEFFAMINE D-205 amine is a good choice for epoxy applications where longer open time and a low exotherm are highly desired.
Features & Benefits
- Low viscosity, color, and vapor pressure
- Lower exotherm and longer pot life than other low molecular weight polyetheramines
- Excellent mechanical properties
- Relatively high glass transition temperature
