Jeff Amine D230 Polyether Amine
Product Information
JEFFAMINE D-230 polyether amine is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, JEFFAMINE D-230 polyether amine is a dysfunctional, 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
JEFFAMINE D-230 polyoxypropylenediamine is one of a family of Huntsman Corporation’s polyamines having as their backbones repeated oxypropylene units. As shown by the above struck- true, JEFFAMINE D-230 is a difunctional primary amine having an average molecular weight of ape- proximately 230. Its amine groups are located on secondary carbon atoms at the ends of an aliphatic polyether chain.JEFFAMINE D-230 is light in colour, low in vis- cosity and vapour pressure, high in primary amine content, and completely miscible in a wide variety of solvents, including water
JEFFAMINE D-230 polyoxypropylenediamine undergoes reactions typical of primary amines. Be- cause of its unique structure, however, JEFFAMINE D-230 has found its most significant use as an epoxy curing agent. The use of JEFFAMINE D-230 leads to tough, clear, impact-resistant coatings, castings, and adhesives. Examples include coatings for decoupage and furniture, reinforced composites, elec- trical encapsulation, and lamination. Coatings made with unmodified JEFFAMINE D-230 are free of the surface “blush” prevalent with many amine curing agents. JEFFAMINE D-230 has found its way into miniature medical devices, industrial floors, boat con- struction, decorator clocks, and space vehicles.Epoxies formulated with JEFFAMINE D-230 can be readily modified because JEFFAMINE D-230 is compatible with a wide range of modifiers and cur- ing agents, including other JEFFAMINE products.
Amidation of JEFFAMINE D-230 with a vari- ety of aliphatic and aromatic carboxylic acids is readily accomplished by known techniques. The re- sulting poly-amides are of interest as “hot melt” ad- hesives, for example.As a primary amine, JEFFAMINE D-230 reacts quickly with isocyanates. The reaction can be man- aged, however, if small quantities are used (e.g., as a viscosity modifier) or if quick-mix equipment (e.g., RIM) is employed.Salts may be formed readily which have poten- tial use, e.g., as surfactants and fire retardants.The reactivity of JEFFAMINE D-230 may be modified by cyanoethylation, a reaction which pro- ceeds readily and cleanly. Polyurea coatings have been made from the cyanoethylated derivative.
