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:
Appearance: Colorless to pale yellow with slight haze
Color,Pt-Co: ≤100
Primary amine:% of total amine:≥90
Total acetyl, m mol/g:6.5-7.1
Total amine, m mol/g:6.1-6.6
Water(%):≤0.25
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.
