What thermal conductivity coefficient should I be using when modelling a heatsink?

Using the finite difference model for heat transfer, I am trying to model the heat flow into a heatsink. However, I am unsure of what k value or coefficient of thermal conductivity to use. Should I be using the coefficient for the material of the heatsink, or of the thermal paste in contact with the heatsink? The image below is the equation I am using.
