Amine-terminated polyether
Zhengda® zd-1200
Zhengda® zd-1200 amine-terminated polyether is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, zhengda® zd-1200 amine-terminated polyether is a difunctional, primary amine with average molecular weight of about 2000. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains.
Applications
Key ingredient in the formulation of polyurea and rim
Co-reactant in epoxy systems which require increased flexibility and toughness
Benefits
Low viscosity, color and vapor pressure
