JEFFAMINE D-230
JEFFAMINE D-230
JEFFAMINE D-230 polyetheramine is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, JEFFAMINE® D-230 polyetheramine is a difunctional, primary amine with an average molecular weight of about 230. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chain.
Applications for JEFFAMINE D-230
- Epoxy curing agent
- Reacts with carboxylic acids to form hot melt adhesives
- Reacts quickly with isocyanates
- Salts may be formed readily for surfactant use
Features & Benefits
- Low viscosity, color and vapor pressure
- Completely miscible with a wide variety of solvents, including water
- Provides tough, clear, impact resistant coatings, castings, and adhesives
- Coatings are free of surface blush prevalent with many amine curing agents
