Polyetheramine D-4000 is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure.
x is a difunctional, primary amine with an average molecular weight of about 4000. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains.
|Appearance||Colorless to pale yellow liquid with a slight haze|
|Color, Pt-Co||75 Max.|
|Primary amine of total amine||95% Min.|
Polyetheramine D-4000 can react as typical primary amines. Due to its fast-reacting nature with isocyanates, it has found wide use in polyurethane and polyurea applications.
In addition, it has found application in conjunction with other polyamines. D-4000 formulated systems exhibit enhanced peel strengths.
And an intriguing application for Polyetheramine D-4000 is in epoxy systems for metal priming via cathodic electrodeposition. However, as the JEFFAMINE D2000 equivalent, other benefits are all same as JEFFAMINE D4000.
