The paste carrier is just a light grease/petroleum jelly or some other carrier of the actual copper powder. That is what's needed in between the faces of the thread form as well as under the face of the nut. The copper keeps the 2 metal parts from corroding together and becoming one. We use this stuff or the Nickel based version on gas turbine casing bolts up to 5" diameter, and they come loose by hand (using a tommy bar about as big as a bic pen) when the tensioner is used to release the loads. These bolts see 1500 degrees-F when in service.
