Jeffamine D-400 Polyoxypropylenediamine 9046-10-0 Huntsman Crosslinking / Coupling / Curing Agents >> Amine Epoxy Resins Marine /Anti-Corrosive / Protective >> Heavy duty (anti-corrosive) Architectural / Decorative Miscible in water Miscible in a wide variety of solvents JEFFAMINE D-400 polyoxypropylenediamine is one member of a family of Huntsman Corporation’s polyamines having as their backbones repeated oxypropylene units. As shown by the above structure, JEFFAMINE D-400 is a difunctional primary amine having an average molecular weight of approximately 400. Its amine groups are located on secondary carbon atoms at the ends of an aliphatic polyether chain. JEFFAMINE D-400 is light in color, low in viscosity and vapor pressure, high in primary amine content, and completely miscible in a wide variety of solvents, including water. JEFFAMINE D-400 polyoxypropylenediamine undergoes reactions typical of primary amines. As an epoxy curing agent, JEFFAMINE D-400 leads to tough, clear, flexible, impact-resistant coatings, castings, and adhesives. In many cases, JEFFAMINE D-400 is used in conjunction with other curing agents, contributing flexibility to the finished product. Compared to JEFFAMINE D-230, the lower-molecular-weight analog of JEFFAMINE D-400, epoxies made with JEFFAMINE D-400 will exhibit not only greater flexibility, but also less shrinkage, slower cure, and lower heat distortion temperatures. JEFFAMINE D-400 finds use in protective and decorative epoxy coatings. Paving and construction uses include seamless floors and crack fillers. JEFFAMINE D-400 can be used in low-viscosity epoxy consolidants and patching compounds for the restoration and preservation of rotted wood. JEFFAMINE D-400, along with its JEFFAMINE analogs, finds use in filament- and matreinforced composites where the end uses range from aerospace components to windmills. Epoxy adhesives having high peel strengths can be made from a combination of JEFFAMINE D-400 and its higher-molecular-weight analog, JEFFAMINE D-2000. Encapsulation of electrical components is another epoxy application for JEFFAMINE D-400. As for nonepoxy applications, JEFFAMINE D-400 finds use in polyurethane RIM (reaction-injection molding), thermoplastic polyamide adhesives, and, as salts, in cutting fluids and fire retardants. Low vapor pressure difunctional primary amine. Used as an epoxy curing agent in protective and decorative epoxy coatings. Provides tough, clear, flexible, impact-resistant coatings. Offers flexibility when used in conjunction with other curing agents. Exibits low shrinkage, slow cure, and low heat distortion temperatures.
