Polyetheramine D-230 is a kind of diamine on the base of a copolymer backbone, its average molecular weight is about of 220, with amino lying in on the second carbon of the polyether end. D-230 has light color, low viscosity, low vapour pressure, and high primary amine content, can be dissolved in various melting agents, and slightly dissolved in water.

Polyetheramine D-400 is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, Polyetheramine D-400 is a difunctional, primary amine with an average molecular weight of about 430. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains.

Polyetheramine D-2000 is a member of the polyamine family having repeat oxypropylene units in the backbone. It is a difunctional primary amine with an average molecular weight of about 2000. Its amine groups are located on secondary carbon atoms at the ends of an aliphatic polyether chain. It is light in color and low in viscosity. Its vapor pressure is extremely low. Polyetheramine D-2000 is completely miscible in a wide variety of solvents.

Polyetheramine T-403 is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, Polyetheramine D-403 is a trifunctional primary amine with an average molecular weight of about 440. Its amine groups are located on secondary carbon atoms at the ends of aliphatic polyether chains.

Polyetheramine T-5000 is a primary polyetheramine with trifunctionality. Its molecular weight is about 5,000. This liquid product is a clear, almost colorless, and viscous. T-5000 has a good toughening effect in the epoxy resin industry.
