Description:

 DHK T-403 polyoxypropylenetriamine is backbones repeated oxypropylene units. JEFFAMINE T-403 is a trifunctional primary amine having an average molecular weight of approximately 440. Its amine groups are located on secondary carbon atoms at the ends of aliphatic polyether chains.

DHK T-403 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.

Physical properties:

Appearance: Colorless to pale yellow with slight haze

Application:

DHK T-403 undergoes reactions typical of primary amines. It is closely akin to another DHK- D-400, and finds use in similar applications. T-403 is used primarily in epoxies, where it has certain advantages over its sister product. Coatings made from DHK T-403, for example, will have somewhat better chemical resistance and color than those made from  D-400.
