NH2CH(CH3)CH2[OCH2CH(CH3)]xNH2 X=*3.1

Description:
Chenhua 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 group 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. Chenhua D****0 polyetheramine is completely miscible in a wide variety of solvents. It is, however, only slightly soluble in water.

Applications:
Chenhua D****0 polyetheramine undergoes reactions typical primary amines. Because of its unique structure, is 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 Chenhua polyamines, Chenhua D****0 formulated systems exhibit enhanced peel strengths.
An intriguing application for Chenhua D****0 polyoxypropylenediamine is in epoxy systems for metal priming via cathodic electrodeposition.
