Amine-terminated polyether Zhengda® zd-140 Zhengda® zd-140 amine-terminated polyether is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, zhengda® zd-140 amine-terminated polyether is a difunctional, primary amine with average molecular weight of about 430. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains. Applications Epoxy curing agent that provides increased flexibility and toughness Used in polyurethanes, polyureas, and thermoplastic polyamide adhesives Salts may be formed for use in cutting fluids Benefits Low viscosity, color and vapor pressure Completely miscible with a variety of solvents Sales specifications Property specifications Appearance, 25°c colorless to pale yellow liquid With slight haze permitted Color, pt-co 50max.
