Description:
Chenhua T-403 polyoxypropylenetriamine is one member of a family of Chenhua polyamines having as their 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.
Chenhua 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:

Primary amine, %of total amine: 90min
Total acetylatables, m mol/g: 6.5min 7.1max
Total amine, m mol/g: 6.1min 6.6max
Water (%): 0.25max
Applications:
Chenhua T-403 undergoes reactions typical of primary amines. It is closely akin to another Chenhua product, Chenhua D-400, and finds use in similar applications. Thus, Chenhua T-403 is used primarily in epoxies, where it has certain advantages over its sister product. Coatings made from Chenhua T-403, for example, will have somewhat better chemical resistance and color than those made from Chenhua D-400.
