Product description

ZHENGDA Amine-terminated Polyether/Polyetheramine ZD-140, which is similar with polyether amine D-400, is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, PEA ZD-140 is a difunctional, primary amine with an average molecular weight of about 430. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains. Polyether polyamine ZD-140 is used for epoxy curing agent that provides increased flexibility and toughness. And it is also used in polyurea systems, epoxy resin, coatings and adhesives industry.
