Property:
D****0 polyetheramine is a
member of a family of polyamines having repeat oxypropylene units
in the backbone. It is a difunctional primary amine with an average
molecular weight of about ***0. Its amine groups are located on
secondary carbon atoms at the ends of an aliphatic polyether chain.
It is light in color and low in viscosity. Its vapor pressure is
extremely low. D****0 polyetheramine is completely miscible in a
wide variety of solvents. It is, however, only slightly soluble in
water.

Usage:
D****0 polyetheramine undergoes
reactions typical primary amines. Because of its unique structure,
it has found wide use in polyurethane and polyurea applications due
to its fast reacting nature with isocyanates. In addition, it has
found application and inconjunction with other polyamines, D****0
formulated systems exhibit enhanced peel strengths.
An intriguing application for
D****0 polyoxypropylenediamine is in epoxy systems for metal
priming via cathodic electrodeposition.
