T-403 polyoxypropylenetriamine is one member of a family of Chenhua
polyamines having as their backbones repeated oxypropylene units. 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. T-403 has 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 property:
1) Appearance: colorless to pale yellow with slight haze
2) Amine value (mol/g): 6.4±0.3
3) Density at 25
oC (g/cm³): 0.98
4) Viscosity at 25
oC (cps): 100±0.5
5) Refractive index (nD20): 1.4550±0.0050
6) Water (%): ≤0.25
7) pH value (5%/w): 11.6
8) Flash point (
oC): 195
9) Amine hydrogen equivalent weight: 81
Application:
T-403 undergoes reactions typical of primary amines. It is closely akin to another
product, D-230, and finds use in similar applications. Thus, T-403 is used primarily
in epoxies, where it has certain advantages over its sister product.
Coatings made from T-403, for example, will have somewhat better chemical resistance
and color than those made from D-230.
