| 摘要 |
This invention provides water-based compositions, particularly coating, ink, and agricultural compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of certain alkylated polyamine compounds of the structures I and II RHN-[(CH2)nNH]p-(CH2)nNHRI where the R groups are independently hydrogen or C5 to C8 alkyl, provided that at least one R is not hydrogen; n is 2 to 6 and p is 2 to 8, and where the R groups are independently hydrogen or C5 to C8 alkyl, provided at least one R is not hydrogen, m is 2 to 6, t is 0 to 3, q is 0 to 3, and r is 0 to 5.
