T-403 polyetheramine is one member of a family of 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 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.
Appearance: Colorless to pale yellow with slight haze
Color, Pt-Co: 50 max
Primary amine, ％of total amine: 90 min
Total acetylatables, mmol/g: 6.5-7.1
Total amine, mmol/g: 6.1-6.6
Water, wt%: 0.30max
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 had 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.
