Waterborne Paint Viscosity Reduction Equation?

  1. Aug 24, 2015 #1
    Hello! I am not sure if this is the right forum to post this in, but I am trying to come up with an equation to predict the viscosity of a waterborne paint after it has been reduced 10% with DI water. The following viscosities were measured at 20*C on a Ford #4 cup, units are in seconds. The viscosity of DI water at 20*C is 9.9 seconds on the Ford #4 cup. These data points were compiled while I was trying to thicken a sample.

    Unreduced / Reduced 10%
    24.5 / 17.4
    25.7 / 18.0
    29.5 / 19.8
    31.9 / 20.9
    36.5 / 23.0
    39.6 / 24.0

    Can anyone help with an equation that would estimate the viscosity when it is reduced 10% with DI water? Right now I'm trying to make a chart in Excel and figure something out with the slope. Not working. Any help that can be offered will be very greatly appreciated!
