Description
ZHENGDA ZD-4000 Amine-terminated Polyether
ZHENGDA ZD-4000 amine-terminated Polyether is characterized by repeating oxypropylene units in the backbone.
As shown by the representative structure, ZHENGDA ZD-4000 Amine-terminated Polyether is a difunctional, primary amine with average molecular weight of about 4000. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains.

Storage&Handling
Amine-terminated Polyether may be stored under air at ambient temperatures for extended periods.A nitrogen blanket is suggested for all storage, however, to reduce the effect of accidental exposure to high temperatures and to reduce the absorption of atmospheric moisture and carbon dioxide. It should be noted that pronounced discoloration is likely to occur at temperatures above 140°F (60°C), whatever the gaseous pad.
Cleanout of lines and equipment containing Amine-terminated Polyether can be accomplished using warm water and steam. In the event of spillage of this product, the area may be flushed with water. The proper method for disposal of waste material is by incineration with strict observance of local regulations.
