Amine-terminated polyether
Zhengda® zd-123
Zhengda® zd-123 amine-terminated polyether is characterized by repeating oxypropylene units in the backbone.As shown by the representative structure, zhengda® zd-123 amine-terminated polyether is a difunctional, primary amine with an average molecular weight of about 230. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chain.
Applications
Epoxy curing agent
Reacts with carboxylic acids to form hot melt adhesives
