NH2CH(CH3)CH2-[OCH2CH(CH3)]xNH2     X=33.1

CAS No.: 9046-10-0

Description:

D-2000 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 2000. 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-2000 polyetheramine is completely miscible in a wide variety of solvents. It is, however, only slightly soluble in water.

 

Physical property:
 Appearance: Colorless to pale yellow with slight haze
Color, Pt-Co:  60 max
Primary amine, % of total amine: 97 min
Total acetylatables, mmol/g: 0.98-1.05
Total amine, mmol/g: 0.95-1.05
Water, wt%: 0.25max

Applications:

D-2000 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 in conjunction with other polyamines. D-2000 formulated systems exhibit enhanced peel strengths.

An intriguing application for D-2000 polyoxypropylenediamine is in epoxy systems for metal priming via cathodic electrodeposition.
