D-2000 polyoxypropylenediamine
equivalent. Polyetheramine D 2000 is a member of a family of
polyamines having repeat oxypropylene units in the backbone. As
shown by the above structure, Polyetheramine D-2000 is a
difunctional primary amine with an average molecular weight of
approximately 2000. Its amine groups are located on secondary
carbon atoms at the ends of an aliphatic polyether
chain.Â
Polyetheramine D-2000 is light in color and low in viscosity. Its
vapor pressure is extremely low. Polyetheramine D-2000 is
completely miscible in a wide variety of solvents. It is, however,
only slightly soluble in water.Â

Package:Â 200kgs/drum
Â
Storage:Â Store it
under air at ambient temperature for extended period.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 temperature above 60℃,whatever the gaseous pad.
